Twitter may limit posts to a mere 140 characters, but it's small size still packs plenty of punch for celebrities to rant, rage and generally "tweak out" online.
Latest case in point: Alec Baldwin, who flooded his Twitter page with angry messages after he was kicked off an American Airlines flight.
"Flight attendant on American reamed me out 4 playing WORDS W FRIENDS while we sat at the gate, not moving," Baldwin tweeted Tuesday afternoon, along with the hashtag, "#nowonderamericaairisbankrupt."
The actor quickly followed that tweet with another "#theresalwaysunited," and then added again, "But, oddly, 30 Rock plays inflight on American."
After catching another American flight, the actor tweeted before takeoff: "Last flight w American. Where retired Catholic school gym teachers from the 1950s find jobs as flight attendants."
By Wednesday night, the actor was apologizing -- somewhat.
In a blog posted on Huffington Post, Baldwin said he was sorry to his fellow passengers while throwing more jabs at the flight attendant in question and the airline industry in general, all the while keeping this deliciously absurd dust-up alive.
"It was never my intention to inconvenience anyone with my 'issue' with a certain flight attendant," Baldwin wrote, adding that he felt "singled out" by a flight attendant and that he was being made an example of, "while everyone else was left undisturbed."
American Airlines was also battling back after being blasted by the actor, saying on its Facebook page that Baldwin not only refused to turn off his phone but got up and took his phone into the bathroom, slamming the door "so hard the cockpit crew heard it." The airlines said the actor was then "extremely rude to the crew, calling them inappropriate names and using offensive language," which is when they had him removed.
After continuing his tirade on another American Airline flight from Los Angeles to New York, Baldwin seemed to have simmered down by the time he landed at JFK and asked his 600,000 followers to unfollow him.
"Let's play a game called Mass Unfollowing," he tweeted. "I want to crash this acct and start again. But, tonight at 10 p.m., NY time, unfollow me." He has since deactivated his Twitter account.
But he managed to get in another swipe at American in his "apology" letter.
"There are many now who walk the aisles of an airplane with a whistle around their neck and a clipboard in their hands and they have made flying a Greyhound bus experience," Baldwin wrote in the post. "The lesson I've learned is to keep my phone off when the 1950's gym teacher is on duty. That was my fault there, even though this trip was quite a bit different from so many others. But it is sad, I think, that you've got to fly overseas today in order to bring back what has been thrown overboard by U.S. carriers in terms of common sense, style and service."

Like Baldwin, film director Kevin Smith aimed his anger at the airlines, specifically Southwest when it removed him from a flight last year for being too fat.
In accordance with Southwest's "customers of size" policy, Smith had purchased two tickets but then stood by for an earlier flight, which had one seat remaining. That is when the airline forced him off the plane.
Smith was irate, tweeting, "So, @SouthwestAir, go f*** yourself. I broke no regulation, offered no "safety risk" (what, was I gonna roll on a fellow passenger?)." When he later boarded another flight, he posted a picture of himself in the seat, writing, "Hey @SouthwestAir Look how fat I am on your plane! Quick! Throw me off!"
Upon landing in Burbank from Oakland, he tweeted, "Hey @SouthwestAir I've landed in Burbank. Don't worry: wall of the plane was opened & I was airlifted out while Richard Simmons supervised."
The airline was not laughing. Southwest tweeted multiple apologies and offered Smith a $100 voucher. He refused the coupon and responded with another tweet: "F*** your apologetic $100 voucher, @SouthwestAir"
Another celebrity who won't be flying Southwest any time soon after taking the airline to task via Twitter is "L Word" actress Leisha Hailey.
"I have been discriminated against by @SouthwestAir. Flt. attendant said that it was a 'family' airline and kissing was not ok," Hailey tweeted in September after she was removed from a flight from Baltimore to St. Louis with her girlfriend Camila Grey.
"This is an outrage. I demand a public apology by @SouthwestAir and a refund. Hate is not a family value. I will never fly this airline," she wrote.
The airline apologized but later justified its actions, saying Hailey and her girlfriend were ousted from the flight for profanity -- not because the actress planted a kiss on her partner.
Singer Chris Brown is no stranger to outbursts.
Earlier this year, he flipped out after "GMA" host Robin Roberts asked him about his 2009 domestic violence incident involving Rihanna.
Last month, he blasted his online critics via Twitter before announcing that he was quitting the social network site.
"Don't say s*** to anybody and everyone feels its cool to attack me. Grown adults! That s*** happened three years ago," he tweeted, according to The Hollywood Reporter. "People please grow up. I've never dealt with so much negativity in my life! It's to the point now that it's just ridiculous!"
Singer Courtney Love's Twitter rampage actually cost her money.
The rocker and widow of Nirvana frontman Kurt Cobain was forced to pay $430,000 earlier this year to settle a 2009 libel lawsuit filed by her former fashion designer, Dawn Simorangkir.
Simorangkir claimed she was defamed by Love's angry tweets, which appeared to be combative, disjointed and littered with spelling errors. Among those cited in Simorangkir's complaint:
"oi vey don't f*** with my wardrobe or you will end up in a circle of corched earth hunted til your dead."
"as one of her many bullied victims smashes her face soon as she's an assault addict herself (there's apparently prostitution in her record too"
Following the settlement, the designer's attorney told The Hollywood Reporter, "One would hope that, given this disaster, restraint of pen, tongue and tweet would guide Ms. Love's future conduct."
Kanye West has no problem speaking his mind, whether criticizing President Bush on live television, or going after Matt Lauer on Twitter after his appearance last year on the "Today" show to apologize for his 2005 comments about the president.
"Yo I really wonder if Matt Lauer thought that s*** was cool to play the "MTV" clip while I was speaking about Bush? He played clips of Bush and asked me to look at his face while I was trying to talk to him I wish Michael Jackson had twitter!!!!!!" the rapper ranted in a series of rambling tweets, referring to the clip of him upstaging Taylor Swift at the MTV Awards. "Maybe Mike could have explained how the media tried to set him up!!! It's all a f***ing set up!!!!"
Demi Moore's soon-to-be ex Ashton Kutcher launched a Twitter war against The Village Voice after the New York weekly ripped apart child prostitution statistics Kutcher had been quoting as part of his "Real Men Don't Buy Girls" campaign.
"Hey @villagevoice REAL MEN DON'T BUY GIRLS and REAL NEWS PUBLICATIONS DON'T SELL THEM," Kutcher (@aplusk) ranted on Twitter in June, addding, "BTW I only PLAYED stupid on TV."
"Wow, @aplusk having a Twitter meltdown! Hey Ashton, which part of this story is inaccurate?" the Voice fired back on its Twitter feed. "Tell us the hard facts you have collected. We'll fact-check for you."
Kutcher continues to shoot from the hip through Twitter. Recently he commented on the collapse of his marriage to Moore, writing, "I will forever cherish the time I spent with Demi. Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK"
