So one night I'm sitting up there, at 2 a.m. at night, and I think there's this question from a student from Pakistan, and he asked a question, and I said, okay, let me go and type up an answer, I don't type all that fast, and I begin typing up the answer, and before I can finish, another student from Egypt popped in with an answer, not quite right, so I'm fixing the answer,
