Bob the Bat was hanging from a tree one night, when his friend Bill flew in and landed next to him. Bob immediately smelt blood, and turns to Bill and noticed blood all around his face. He excitedly asked Bill, "Where did the blood come from? Did you find a good meal"?
"No I didn't," Bill says.
Bob tried again, "C'mon Bill I wont tell anyone, where's the meal you found?"
Bill replied, "There's no meal Bob."
This continues for five minutes until Bill said, "Follow me, I'll show you."
After flying for several minutes, Bill flies next to Bob and asks, "See that big tree up ahead near the river bank"?
Bob says, "Yeah, yeah."
Bill says, "Well I f@#k'n didn't!"
