Get to the scene where Jonathan Brandis just gets out of school and is talking to his friend in the hall. He notices kimerly(the "hot blonde"). Jonathan Brandis' friend has a football and tells Jonathan's character to go long for a pass.In doing so Jonathan Brandis sets down his backpack, runs for a pass, catches it in front of the girl, and then gets up to see Chester is there to pick him up. While walking along side of the car he miraculously has his backpack back on. The same one, i might add, that he dropped back by his friend.
