A student died and he moved into the hell. It's a beautiful life there:
prostitutes, wine, grugs. But in the evening the devil comes and puts a big
nail into the student's ass. The student has been lived in the hell for a week
and the devil talks him:
- I can move you into the student's hell! Wanna try?
- Sure!
Now the student's living in student's hell. His life is wonderful:
prostitutes and so on... And... Nobody comes in the evening with a hammer and
nails. The student has been living in that manner for about a four month.
Suddenly the devil comes to him with the BIG bag of nails and the huge
hummer. The student asks him:
- What is mean? Why do you have so many nails? What's up?
- It's finals... Right now...

A student's taking an exam. The teacher asks him:
- Have I seen you before? (or "I have seen you before, haven't I(?)" It
must be something like this "You're engaged. Aren't you?")
- Well.. Yes. I've been taking the exam last year. And I didn't pass it.
- Do you remember, what was my first question?
- I guess, you've been said: "Have I seen you before?".
