You know what would be funny? You cover up your face, run in a bank with a realistic looking toy gun, wave it around and say funny things like 'Put all the money in the bank!' or 'Shut up or I'll shoot you in the face!' and then just stop, laugh, take off your mask and exclaim loudly, 'JUST KIDDING!' and then take a number. Sometimes people need comedy thats out of the blue.
