 In this quiz format, teams of two from the public at large answer questions, with this twist that one must buzz, but may not answer - hence the title which refers to the Dutch expression which literally translates as "knowing one s Pappenheimers", i.e. know (at the feudal general Wallerstein, who levied some troops from his native Pappenheim) well who one deals with. After the first round, each team gets to choose blindly a third member from a small pool of Dutch-languages celebrities, only hearing their voices and answers to a few questions probing their interests; the captain (a non-celebrity) must now decide who answers the questions before they are known, based on the announced categories. After team elimination, the members of the finalist team must each answer questions in a race against the clock, wrong answers meaning the number of questions is augmented.
