Actor Steve Buscemi has signed on for another guest-starring stint on the NBC comedy series 30 Rock. The actor will reprise his role as private detective Len Wosniak in the February 16 episode. Here's what creator/star Tina Fey had to say about that episode's plot line.

"After Jack (Alec Baldwin) gets mugged, he tries to reach out to his connections on the police force, [saying,] 'I know Commissioner Ray Kelly. We have a column in Irish Arguments Weekly, the only all-caps magazine. But he hasn't gotten back to me on this.' Jack wants Len to help him form a private police force where the salary starts at $5 million, so the police have the same interest in protecting the rich."
