Das weiß doch jedes Kind!

Grown-up contestants have to answer to ten questions of school knowledges of the first five grades. In this "classroom" there are also 5 students at the age of 10-11, who the contestant choose one and becomes his "bank-neighbor". So, the bank-neighbor can help him, if he doesn't know any more. In detail the jokers are: "Lard": The contestant can have a look to his bank-neighbor, what he has written and can decide, if he take his answer or another one. "Crib": The contestant has to take the answer of his bank-neighbor. And the "Last Rescue": If the contestant has given an answer and it's wrong, his bank-neighbor can helps him to stay in the classroom (in case of his bank-neighbor has the right answer). If he has no joker any more and he answers wrong, or he leave the school instead to answer, he must to say "(translated:) That knows yet every child, but I just not".
