A guy who is really too smart, and he is being harassed at school.
So he decides to go see a doctor and asks him to remove a little bit of brain.
The next day, the guy comes back and asks the doctor to remove the double of the little tip that he had removed the day before.
The third day, the guy comes back, desperate and asks to take away his brain and leave him a tiny bit of nothing at all.
The doctor tells him:
- Okay sir, but tomorrow you may start menstruating!
