In the Academic Bowl episode of SBTB, Zack tells
the nerds on Valley's team that Bayside is going to
choose the category of football. But he actually chooses
basketball, thus thwarting the nerds' list-memorizing
attempt. Then Zack wins the match by using the mnemonic
taught to him by Screech...what the order of the 9 nine
planets are. It is a very touching and always
unpredictable story.
