Conan O'Brien with Will Ferrell as a stripper leprechaun

Conan O’Brien will be back on television June 1 when he officially begins hosting the Tonight Show and he has announced his first episode guests.

The first ever guest on the show will be actor and comedian Will Ferrell, who has appeared on Late Night dozens of times, usually ending with him doing a striptease as a naughty leprechaun. (No word on whether that bit will survive the earlier time slot.)

And the first ever musical guest on Conan’s Tonight Show will be Pearl Jam. (No word on whether Pearl Jam, is still around, heh.)

Hurry up, Conan! I enjoy Jimmy Fallon, but Jay Leno has to go (to 10pm)!
