Well, once, in science class sometimes, we would do a "jeopardy" sort of thing, where we'd be in groups of 3 or 4, and the teacher would use a projector to show the amount of points you could get for each question, and whichever one we picked, it would show the said question.
(Since it would say x points, then we pick the row and points and it shows a question.)
Unfortunately, if your group talked too much, you'd lose 10 points. So, when one of my annoying friends saw that me and my other smart friends ALWAYS won, he came to our table.
Which resulted in him not shutting up ever, making us lose a whooping 60 points at the end.
Midway though, one of my friends said, "SHUT THE F-" when the teacher gave him a glare.
"...FRONT...DOOR."
And my group got 2nd place that day.
