According to Zach Galifianakis, pregnant bombshells are more than fair game when it comes to a major diss. In a recent interview with ShortList.com, when 'The Hangover Part II' star was made aware that January Jones named him as the funniest man she'd ever met, he was quick to call out the 'Mad Men' beauty on what sounded, to us like a compliment.

But Galifianakis remembered a more than "rude" mama-to-be when he was summoned to her table at an event.

"I sit at her table and talk for 10 minutes, and she goes, 'I think it's time for you to leave now,'" Galifiankakis recalls. "So I say, 'January, you are an actress in a show and everybody's going to forget about you in a few years, so f-cking be nice,' and I got up and left."
