Once we were talking about number prefixes at our table, and I was wondering which number was "love-" and then the table next to us screams "ARE YOU TALKING ABOUT love?!". Also, once they said that we were lame or something, then I said "Sure, whatever." and then a kid there screams "YOUR MOM!" Then, I said "I'm sorry, that is not a valid argument." And the kid was calling me a nerd then.
