Ok, I promised myself I would never tell this one, but, what the heck.
One guy is telling his friend about his new talking dog, but of course, his friend's a little skeptical.
Dog owner: "No, really, he can talk. Here let me show you. Spot, what's that on the side of the tree?"
Spot: "Bark!"
Friend: "Hmm, I don't know.."
Dog owner: "Ok, let's try this one. Spot, what's that on the top of the house?"
Spot: "Roof!"
Friend:
Dog owner: "I know, but this should really prove it. Spot, who was the greatest baseball player ever?"
Friend: "Ok, ok, he's going to say Ruth, right?"
Spot: "No, actually I was going to say DiMaggio."
