Starving Men On An Island

There are two starving men stranded on an island with only a rusty old knife. The first man says, “Well, I think our only choice is to eat each other's legs. We're not walking around, anyway. And we need food”. The other man agrees. So the first man begins sawing and crudely cutting the other man's legs off. I after about an hour of excruciating pain, the second man's legs are completely off of his body, so he says, “Okay, your turn. Give me the knife”. So the first jumps up and runs away with the second man's legs, saying, “You'll have to catch me first!”
