That's Hell
A guy goes to hell and is met by the devil, who explains that the punishments are changed every thousand years and he is to select his first punishment.
First room has a young guy on the wall being whipped.
The new guy not keen on this asks to see the next room.
The next room has a middle aged guy being tortured with fire.
The new guy immediately asks to see the third room. It has an really old guy chained to the wall getting a blow job from a gorgeous blonde.
The guy jumps at the chance and takes the room. The devil walks into the room taps the blonde on the shoulder and says, "Okay, you can stop now, you've been relieved".
