Barking Dog

A kid brought his dog to school. At show and tell, when it was his turn in front of the class, the teacher asked, “What have you brought?”
“I’ve brought my talking dog,” the kid replied.
“Oh?” said the teacher. “And what can your talking dog say?”
The kid leaned down to the dog and said, “What’s on top of a house?” The dog immediately said, “Woof!”
The class groaned. “That was too easy,” the teacher smiled. “Can your dog say anything else?”
The kid leaned down and said to his dog, “What’s on a tree?” The dog replied, “Bark!”
“Aww, way too easy,” everyone said. “Anything better than that?”
The kid leaned down to the dog and said, “What do my little brother and sister do during dinner?” The dog replied: “Yap! Yap!”
The class groaned louder. The teacher said, “Thank you for bringing in your dog, but maybe those are just dog sounds, not really talking, hm?”
Another kid from the back of the class piped up, “Yeah, maybe if he knew French or something, it might have impressed us a little more.”
