Another bad joke

Two young boys were sitting on a porch during a hot afternoon, drinking glasses of iced tea. Their hound dog sat between them on the porch floor, licking his old dangling hound balls.

One boy smacks his lips and looks down at the hound that was lost in his licking. “I wish I could do that,” the boy says to the other boy.

The other boy said,” you probably could, but I’d pet him first.”
