Hey, Conan, what are you doing Sept. 25?
If you aren't busy, a young bride-to-be and her betrothed wonder if you might be his best man? Just think about it. You'd look good in a tux.
For Sarah Killen and John Slowik Jr., having the former late-night, talk-show host standing at their wedding would be the perfect cap to the strange journey they've taken in the past few days since O'Brien picked Killen at random to follow on Twitter.
"We went from being really hard up and now we have thousands of people trying to help us," Killen told "Good Morning America" via Skype, the Internet phone service.
The young Michigan couple, who have been together for about three years and planning a low-budget September wedding, have been flooded with offers for wine, desserts, a dress and even a honeymoon. Not bad considering they had saved up $30 on their own so far.
All because O'Brien picked Killen, who had just three followers on Twitter, to follow.
He announced his choice Friday with the tweet, "I've decided to follow someone at random. She likes peanut butter and gummy dinosaurs. Sarah Killen, your life is about to change."
And change it has. The 19-year-old bride said she and her fiance had saved up $30 for their wedding before O'Brien's announcement. Now they are asking all Killen's new followers (she has more than 20,000 now) to donate money to the Susan G. Komen foundation before their August walk with Killen's mother in Detroit to benefit breast cancer research.
O'Brien posted a message for her again on Wednesday night after her interview got bumped on CNN's "Larry King Live."
"OMG!" he tweeted. "My pal Sarah got bumped from Larry King for something called "Breaking News." Has the whole world gone insane?!"
Killen said she only joined Twitter a couple of weeks ago because Slowik had done so, figuring few people would want to read what she had to say.
After O'Brien's post on Friday, she gained 160 new followers in minutes, at a rate of two per second. They have read about everything from her news appearances to tweets about Oscar night.
Even Slowik's star has been rising. He has gone from 13 followers to about 450. He gets more followers every time Killen mentions his name.
