Fishing with Jack
A man is going fishing one day. After awhile, he runs out of bait. He sees a snake nearby with a frog in its mouth. Knowing that a frog will make good bait, he catches the snake. He removes the frog, and thinks to himself, "How do I let the snake go without getting bit?" He ponders for a minute, then, with his free hand, reaches for his bottle of Jack Daniels whiskey. He pops it open and pours some in the snake's mouth. The snake goes limp and the man tosses it away. Later, as he is getting ready to go home, he feels something on his foot. The man looks down to see the snake next to the whiskey, this time with two frogs in its mouth.
Q: What do you call a bird that's afraid of heights?
