A guy dressed in regular street clothes walks into a bar on Halloween and orders a beer. “I’m here for the costume party,” he tells the bartender.
The bartender looks him up and down, taking in his ordinary clothing and no makeup or wig. “What are you supposed to be?” the bartender asks. “I’m a werewolf,” the guy replies. “How’s that? You’re not dressed up at all,” the bartender says.
“Well, it’s not a full moon tonight, now is it Mr. Smart Guy?” the guy replies.
