Today was a joke:
Prepod as it accepts: you go to it, it takes the count and asks the number from 1 to 50, this is the type of number of task that you need to solve.
So here, one of our FIFA comes to him, gives a clue, then there is a dialogue:
Prep: Name a number from 1 to 50.
Oh, what an easy task!
I went to comp. The group barely got off the chairs)))))
