A computer scientist stands at the gates of heaven.

Peter: With you, I really could not decide whether you should go to heaven or hell. It is best if you take a look at both sides and decide for yourself.

Peter shows him a seemingly endless room with the fastest computers, where the computer scientist is allowed to programme everything to his heart's content.

That is fantastic, says the programmer, and for the sake of completeness also wants to know what hell looks like.

Peter replies: 'Hell is also here, the only difference is that you are not the programmer but the administrator!'
