In my undergraduate days we'd pass around an attendance sheet when the professor was more than 15 minutes late for class. Then we'd leave and get credit for being there. In addition to our own names, we'd write in such luminaries as Bunny Easter, Forrest Greene, Nipon Tucker, U.R. Absent, Yellow Snow, and (in those days), Ed Sullivan.
However, the name I enjoyed most was "Sam Orez". In my first years of teaching I had a group os students that were sharp and witty. For each exam or quiz, SOMEONE would claim he or she didn't get a copy of the material and would take the quiz under the name of "Sam Orez"--who always got a failing grade. There wasn't a student by this name on my roster, still Sam took every test and quiz. On the short answer quizzes, Sam gave the most bizarre answers. (Example: Who wrote HEART OF DARKNESS? Answer: Lola Falana)
It wasn't until mid-terms that I realized HOW the class was managing this, and it wasn't until year's end that I was told "Orez" is actually "Zero" spelled backwards.
