I watched a film that had the main protagonist attending a conference where the (iirc) American president was making a speech.
The speech referenced the politician doing different things and getting a number of votes from a specific states. As the joke progressed he would get more and more votes until the punch-line was something along the lines of 'smoked pot in college; California 20,000 votes'.
Please help me to find this film, it's driving me mad now!
