Dear Faldage: In the old country schools, if a pupil needed to void, he held up one finger to indicate he needed to leave the room for the little house out back. If he held up two fingers, that meant he would need to be gone a bit longer. The teacher knew number one was yellow, and number two was brown, but was glad she did not have to smell them The jocks still use the old terminology when they announce their intention to "do a number" on their opponents.
