A guy dressed in regular street clothes walks into a bar on Halloween and orders a beer.
He tells the bartender “I’m here for the costume party,” .
The bartender looks him up and down, taking in his ordinary clothing and no makeup or wig.
The bartender asks “What are you supposed to be?”.
The guy replies “I’m a werewolf,”.
“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.
