A joke my brother made up when he was 13... Two men were marooned on an island with no food. After a week, they are both starving. To solve the issue of hunger, one of the men suggests that they cut off each other's legs and eat them to survive. The other man agrees. The first man, after a bloody and gruesome struggle, saws off the second man's legs. The second man, pale and weak, says to the first man. "Alright, now let's get your legs off" The first man runs away and yells "you have to catch me first!"
