It's pretty safe to assume Zach Galifianakis' name can be crossed off the long list of January Jones' possible baby daddies.

The star of The Hangover, Part II, recalled his irritating encounter with the expectant Mad Men actress in an interview with Shortlist recently:

"[January] and I were very rude to each other. It was crazy. I was at a party — I’d never met her — and she was like, 'Come sit down.' So I sit at her table and talk for ten minutes, and she goes, 'I think it’s time for you to leave now.'"

What did the comedian respond with?

    "So I say, 'January, you are an actress in a show and everybody’s going to forget about you in a few years, so fucking be nice,' and I got up and left."

But that's not the end of it ... Galifianakis adds that if a script were offered to him requiring a sex scene with the actress, he wouldn't want anything to do with it.

    "I wouldn't want to. I'd hate it."
