So if Mel Gibson's not in The Hangover 2...then who is?

Quickly....

I think we all grimaced a little bit at the idea of Mel Gibson making a cameo in The Hangover 2, but obviously none moreso than the cast who quickly shot the idea down. So if Mel Gibson's not making an appearance, who is? The answer? 

Liam Neeson. Neeson, who most recently was seen in The A-Team and the erotic thriller Chloe, confirmed he got the call and was more than happy to jump at the opportunity. He's a fan, apparently.

Neeson: "I just got a call to do a one day shoot on 'Hangover 2' as a tattooist in Thailand, and that's all I know about it," Neeson told Daily Variety. "I just laughed my leg off when I saw 'The Hangover, I was shooting in Berlin earlier this year and rented it on the hotel TV."

Not exactly Mel Gibson level celebrity, nor does he have the tainted public persona like Mike Tyson did, but Neeson should be a welcome addition.
