Bill Hader is a deeply sexual being from another dimension sent to cheer up us poor earthlings through his acting, directing and sometimes musical work.

You should definitely listen to the Blue Jean Committee at New York's hottest club.

A spankin' new cast member on Saturday Night Live. He is an long-time improviser, and when performing a show at a low-budge theatre in LA, he was discovered by Megan Mullally who passed his name on to Lorne Michaels, hence got an auditio n for SNL and triumphed because he is fucking amazing. Undoubtedly the next Will Ferrell. Supersedes Andy Samberg (other new cast member this season) by-far.

ps- He's a doll in person (see my picture with him)
