Amused by this distinction, he said, "If I beat CNN to 1 million followers I will literally go and ding dong ditch Ted Turner's house while I'm in Atlanta." (Kutcher will soon film "Five Killers" in the city, with Katherine Heigl and Tom Selleck.)
Before the actor signed off from his YouTube missive, he had some words for his acolytes: "To everyone who is following me on Twitter, you guys are awesome, and I just really enjoy the conversation we can have every day."
It didn't take long for his fans to respond with similar appreciation.
Soon after Kutcher posted his YouTube link to his Twitter feed, the Twittersphere was abuzz with his new challenge.
His followers started re-tweeting his post and asking others to join the campaign.
"SwissCow86" wrote: "U should ask ur followers to remove CNN from their "Following" :)"
"LaurenDayMakeup"called it the "Ding Dong Dash 2009."
"1 Million Followers Campaign Everyone PLEASE FOLLOW him! 855,472 so far! please retweet," she wrote.
Even Olympian Michael Phelps has offered his support, encourging his 75,244 followers to help boost Kutcher's numbers. On Wednesday, he tweeted: "Guys, let's all help Ashton win the race to a million!"
Spotting an opportunity, video game published Entertainment Arts also decided to jump in and sweeten the pot.
On its own Twitter account, it wrote that Kutcher's one millionth follower will get a copy of every game the company makes in 2009 and would be featured in its upcoming game, The Sims 3.
And, Don Dodge, a Microsoft employee and tech blogger recently wrote that he thinks Kutcher might go down in Internet history as the first individual Twitter user to hit 1 million followers.
When he first wrote about celebs on Twitter in early April, Kutcher had 521,469 followers. But in just two weeks, he surpassed 753,000.
"He'll certainly be the first individual to reach a million followers. He may even beat CNN," Dodge told ABCNews.com.
He calculated that Kutcher is adding about 15,000 followers every day and expects him to have a million followers by April 21.
