I've been cought several times. One time I was in my room doing it, and I thought I was home alone, so I had my door open. I had told my parents I was going to be studying. So, I was doing it and all of a sudden I heart my dad say "I thought you were supposed to be studying." Then he just walked away. I didn't really care, it just shocked the hell out of me.
It's a funny story now though.
