A man walks into a bar with his pet giraffe and they both sit down at the counter. The bartender looks at them in surprise and says, "Hey! You can't bring that in here!"
The man looks at the bartender and says, "Oh, don't worry, he's very well-behaved. In fact, he's a talking giraffe. Watch, I'll prove it to you."
He leans over to the giraffe and says, "Hey, what's the thing on top of a house that keeps out the rain?"
The giraffe looks at him for a moment and then says, "Roof."
The bartender is amazed and says, "Wow! That's incredible. But wait, let me ask you another question. What's the thing in the middle of your face that you see out of and breathe through?"
The man looks puzzled for a moment and then says, "Umm…nose?"
The bartender starts to laugh and says, "Haha, that's right! You really do have a talking giraffe. But tell me, how did he know the answers to those questions?"
The man shrugs and says, "Oh, he just knows a lot of random facts. But hey, enough about the giraffe. What's the special for tonight?"
