Bob dies and goes to hell.
The devil calles him for a visit, in which he explains how things work: there is a selection of three punishments from which you have to choose one. The punishment change every thousnad years.
In the first punishment room there is a young guy on the wall being whipped. Bob, who is not keen to spend a thousnad year like this, asks to see the next room. There he see a middle aged guy being tortured with fire.
Bob immediately asks to see the third room. It has a really old guy chained to the wall getting a blow job from a gorgeous blonde.
Bob 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".
