9. The 40 Year Old Virgin
Following a middle aged man in his desperate attempt to get his end away isn't necessarily the most endearing movie pitch we've ever heard. But Andy Stitzer (Steve Carell) is no womanizer; indeed, it's his first time. And while we're hardly surprised to find the film closing under the covers, nobody could have predicted an, erm, climax such as this. Having consummated his marriage to Trish (Catherine Keener), Andy wakes the next morning a new man. His wife, still breathless, asks ''So, how was that for you?'' And in response, Andy stares at the ceiling- his face the very picture of post-coital bewilderment- and begins to sing: ''When the mooooon is in the seventh house...'' Yep, it's the opening lines of the 'Hair' medley 'Age of Aquarius/Let the Sunshine In'. Each to their own, but crooning along to Sixties musicals is a rite of passage I'm not that familiar with. He then turns to the camera, perhaps a little too close, and grants his audience the most awkward serenade imaginable. This quickly morphs into a fully-fledged song-and-dance routine, wherein members of the cast prance about upon a hillside until the whole thing resembles an ad for a new brand of fabric softener. It's as bafflingly brilliant as it sounds.
