In class the guy next to me leans over and says: Hey can I ask you a question?
Confused guy: Aren't there normally more guys in this class than three?
Me (scanning the classroom of about 100 girls): Hmm.... in this class? Nope pretty sure that's all of them.
Confused guy: Wait... what class is this?!
Me: Elementary Ed framing seminar.
Confused guy: I knew it didn't seem right!
Hahahaha. I don't know how he went to the wrong classroom halfway through the semester but it made my day.
