Jerk Waiter

Go to an Italian restaurant, one that preferably caters to old people. Order spaghetti with meatballs. When the waiter brings you your food, tell him this is not what you ordered and get very angry. Start screaming about how you ordered a steak. Then pick up a huge handful of the spaghetti and push it into a random old ladies face make sure you get it all over her. Then scream at the waiter, "does this look a steak to you!?" Turn to the lady's husband and say, "man, this waiter is such a jerk" and then just walk out.
