I went up to some random guy and said "Now i must tell you a joke." A mushroom hops into a bar and tries to order a drink. The bartender gets very angry and starts yelling at the poor mushroom to get out. The mushroom trys to appeal to the bartender, hops onto a stool, and says "Come on, let me stay - I'm a fun guy!" Understandably, the stranger said, "Okay, it's time for me to leave now." He bolted before I could ask him to tell me a joke.
