In honor of April being National Humor Month, I'm sharing one of my favorite stories with you.
A guy in a bar says he has a talking dog. "Prove it," says one of the regulars.
Guy turns to the dog and asks him, "What's on the top of a house?"
Dog replies, "Roof, roof!"
"Oh, come on," says the regular.
Guy asks dog, "What's on the outside of a tree?"
Dog says, "Bark, bark!"
Regular says, "You must be kidding."
