I was one of the only people with plugs in at my holiday party this year; then when I was leaving and walked outside, as I was taking them, a group of people said, literally, 'holy F*** are you smarter than I am, it was f'ing LOUD in there.....'
On a similar note, I'm generally the first person to fasten a seatbelt on group rides, because once you total a few cars it sort of sticks with you...
