LOS ANGELES (Hollywood Reporter) - If Conan O'Brien's debut on Twitter is any indication Coco fever is stronger than ever.

In his first public comment since his final Tonight Show on February 12, O'Brien launched a Twitter account Wednesday afternoon, (at)conanobrien, and sent his first tweet. Today I interviewed a squirrel in my backyard and then threw to commercial. Somebody help me, he wrote on his page, which also includes his bio summed up as I had a show. Then I had a different show. Now I have a Twitter account.

What followed was a wildfire on the microblogging site. Within the first three hours, O'Brien had more than 100,000 followers, with 1,000 new fans signing up every minute.
