One day a duck was flying through the sky searching for something to eat. It saw a frog hopping around on the ground and quickly swooped down and swallowed the frog.
The duck took off into the air and digested the frog. About an hour later the digested frog poked its head out of the flying duck's ass, looked down and asked, "Hey duck, how high are we from the ground?
The duck answered, "Oh about 20,000 feet".
To which the frog replied, "You wouldn't be shitting me now, would you"?
