A man walks into a bar with a parrot on his shoulder. The bartender says, "Hey, that's pretty cool! Where did you get him?"
The parrot responds, "I got him at the pet store. They were having a special: buy one, get one free!"
The bartender laughs and says, "That's great! What's his name?"
The man grins and says, "His name is Trouble. And let me tell you, he lives up to it! This little guy is a troublemaker through and through."
Just then, the parrot squawks, "Oh, shut up, you old windbag! You're the real troublemaker around here!"
The bartender bursts into laughter, and the man looks embarrassed. But then the parrot says, "Hey buddy, don't worry about it. You may be the one buying the drinks, but I'm the one making everyone laugh!"
