Not mine, but I had to share...

A bus full of politicians crashes on the side of a farm road and before the authorities can get there, the farmer and his sons come out and bury them all. When the emergency services do arrive, the sheriff says to the farmer, "You mean to tell me they were all dead?" And the farmer looks the cop right in the eye and says, "Well, some of them said they weren't, but you know how those bastards lie!"
