It was July 4th, the parade was over, but unfortunately the fireworks had set a 10 story building on fire. Two men who had been watching the festivities were trapped on the roof. The fire ladder couldn't reach them, and there was no other way for them to get down. Looking down, they spotted a pile of shit where the horses had been kept.

One man looks at the other and says, "We'll die if we stay here. You jump into that pile of shit first, then yell up to me how deep it is." The second man agreed and jumped. He yells up, "It's knee deep!" The guy thought, that's not too bad, and jumped.

He landed in the pile of shit and sank up to his neck. He looked at his friend and said, "You said it was only knee deep!". His friend replied, "Oh, I jumped head first."
