At the risk of being given a caution for going offtopic; don't you just love nodding to the music you're listening to in say, your headphones, when someone's asking a question and would preferably want a "yes"? And even though they think they've just been given one, you were actually just nodding to the rythem... So that later when they ask about it you can just say "I was nodding to the rythem of the music, and couldn't hear a f
ucking word you were saying".
