One of the scenes in Forgetting Sarah Marshall that people will be talking about over the virtual water cooler next week is the one that involves Jason Segel doing full frontal nudity. Yes, he lets it all hang out, and what's admirable is that he does it purely for the sake of a joke. That takes courage! That takes guts! That takes ... well, you know.

This isn't the first film to use nudity for laughs, of course. Comical naughty bits have a rich history in Hollywood. Here are seven movies with hilarious nudity.

What's funnier than a naked dude? A naked FAT dude. And what's funnier than a naked fat dude? A naked fat dude wrestling a naked skinny dude in a hotel room, and a hotel hallway, and a hotel elevator, etc., etc.

Are you ready for Leonardo DiCaprio doing an Irish accent? He probably should have played Irish in Titanic, but now he'll really have to master the accent for a historical epic called Freedom Within the Heart. Set 1,000 years ago, the film is about Brian Boru, the High King of Ireland who united the country in battle against a Viking threat. Since Boru was at least 60 when he became King, DiCaprio seems a bit young to play the lead, but according to a story from February, the actor was indeed being sought for that very role. At the time, former soccer pro Vinnie Jones was also reportedly cast as Boru's nemesis, Ivor of Limerick. Now, confirming DiCaprio's involvement is a press release from Limerick.com, which states the two actors will be joining Irish filmmaker Mark Mahon in the village of Tuamgraney, in County Clare, provided the Irish Film Board accepts a bid for the production to shoot there. There are hopes that the movie will bring tourism to the area in the same way movies like Braveheart and Rob Roy have brought people to Scottish locales.

Despite earning an Oscar nomination for Blood Diamond, a lot of people thought he did a terrible job with the South African accent, so we'll have to see how he does with the Irish. He could be criticized enough for playing such a legendary figure and not actually being Irish, so if he gets the accent wrong, he'll only make things worse. However, plenty of similar epics have been made without great accuracy, and fans of medieval action probably won't mind.

Say what you want about Mel Gibson and his recent run in with the law, the Jews and the bottle, but the dude definitely knows how to paint a pretty picture up on the big screen. Visually, the guy is a genius -- I mean, Braveheart will forever rank high up on my "fun flicks to watch when you feel like kicking the crap out of someone, but can't" list. Same goes for The Passion of the Christ, though, being Jewish, I wouldn't consider myself a member of the Jesus fan club, however Gibson certainly knows how to garner a reaction from an audience through the power of the moving image.

Case in point: The first theatrical trailer for Gibson's upcoming Apocalypto is now available online and, let me tell you -- the thing looks pretty fricking sweet. Set during the downfall of the Mayan Empire, the story revolves around one man's decision to flee his home after he's chosen to become a human sacrifice. While the pic probably won't do a ton of business for Disney (partly due to the whole drunk-driving episode, and also because the film's characters speak in an ancient Mayan dialect), I've decided to check it out based solely on the beautiful, yet awe-inspiring images included in this trailer. Apocalypto's release date was recently moved to December 8 (a day Disney insists will stick), and so we'll soon find out what the world really thinks of Mel. Will you shell out ten bucks for this?
