Sassy Chem Guy

A guy in Garrison's 5.111 recitation, whose real name was, let's say, Robert. When the TA was handing the first test back and asked "who's Robert", Sassy Chem Guy raised one of his previously crossed arms and responded, "uhh, me" as if it was a great insult that the TA and, for that matter, everyone else in the world was unaware of his name and greatness. Sassy Chem Guy briefly dated Elevator Girl.
