"Saturday Night Live's" latest victim is MSNBC's Keith Olbermann. The sketch show is moving on from Governor Sarah Palin to poke fun of the news anchor -- at least temporarily!

Politico.com reported Ben Affleck was rehearsing a skit mocking the newsman on Friday. Olbermann was able to get past security and watch! Affleck was portraying Olbermann as a "deranged person living at home with his mother."

An Olbermann spokesperson said there are no hard feelings. The anchor said, "I'm not Sarah Palin. I know how valuable it is to me. And it's funny."

Affleck hosts "Saturday Night Live" tonight with musical guest David Cook and a special appearance from Senator John McCain.
