2. Jennifer Lawrence  Cougar Mascot, Monk

The Hunger Games star may be one of the hottest actresses in Hollywood right now, but her breakout role left her red-faced after being shown during her appearance on Conan O'Brien earlier this year. Lawrence reveals she told everyone she knew about her first acting role in US comedy-drama Monk, and that they should watch out for it. Unfortunately, she didn't realise the role she was actually playing was inside a cougar suit as a mascot at a high school basketball game. Her scene is at a high school girls basketball game, where she jumps and claps and gets the crowd going. She even jumps on Mr. Monk in her excitement at playing her very first mascot, but naturally he doesn't take it very well, presumably worried about all the bacteria infesting the cougar's fur. It hardly qualifies as an acting role, although she is given a speaking part comprising nine whole words, and a name: 'Jen'. To her credit, Tony Shalhoub has never had his arm fake-mauled that well before.
