The Zoo and the Shih Tzu

Okay, listen up, you dummy. You, who posted this, probably think you're real funny, huh? Let's break it down for your teeny tiny brain. A man goes to a zoo, right? But instead of lions and monkeys, there's only a dog. Now here's the punchline, it ain't just any dog, it is a "shih tzu." Get it? It sounds like "shit zoo". You're not laughing? Well, I am not surprised.
