2. Mike Tyson in The Hangover
The Hangover still stands up as one of the best comedy films of the last 10 years or so, and with good reason. The laughs come thick and fast as Bradley Cooper, Ed Helms and Zach Galifianakas try to recount what was clearly a R-Rated night out in Las Vegas, encountering strippers, drug dealers and all manner of hilarious situations along the way. But arguably the film's most memorable sequence features a certain Mr Tyson. As our hungover heroes search desperately for their lost friend, they enter their trashed hotel room, to find Mike Tyson, former heavyweight champion of the world, singing horribly along to the Phil Collins track "In The Air Tonight", before delivering a classic knockout punch to Alan's face. That hilarious introduction aside, his facial expressions as he watches the security tape are priceless, but the icing on the cake has to be the moment when he starts getting along with the gang, proclaiming wisely that: "We all do dumb sh*t when we're F***ed up!" Perfection. http://www.youtube.com/watch?v=ELc9Aw3fS-g
