Ashton Kutcher is famous for being able to give it, but apparently he can’t take it. Kutcher, the actor/producer who has become a pop icon for his usage of Twitter (and the first account to have a million followers) is threatening to leave the service if a plan goes forward to use the 140-character microblogging service to track celebrities in a new reality show.

Ashton Kutcher said he might give up Twitter if the Web site’s parent company participates in a reality show.

“It’s all fun and games until somebody gets stalked,” Kutcher wrote in a Twitter posting late Monday.

Variety magazine reported Monday that San Francisco-based Twitter.com had partnered with TV producers Reveille and Brillstein Entertainment on an unscripted show that would be “putting ordinary people on the trail of celebrities in a revolutionary competitive format.”

Twitter co-founder Biz Stone said there was “no official Twitter TV show” in the works, but “we have a lightweight, non-exclusive, agreement with the producers which helps them move forward more freely.”

Kutcher used Twitter to post a link to a news report about the partnership along with this message: “Wow I hope this isn’t true. I really don’t like being sold out. May have to take a twitter hiatus.”

I find it somewhat amusing to see that Kutcher, who wasn’t afraid to do anything to advance his career via Twitter – including breaking into the CNN Center to hang a banner with his twitter account on it – is suddenly finding out what it’s like on the other side. There’s those old sayings about karma being a bitch, or what goes around comes around – well, I’d say this is “Punk’d” getting regurgitated right on his shirt.

C’mon, Kutch – where’s the sense of humor? Didn’t mind making someone else look like an ass on TV – or posting your cougar wife’s ass on TwitPic – but as soon as you don’t control the situation you cry foul? Man up, boy – man up!
