As others have noted, but somewhat obliquely: Basketball players almost always know for certain whether or not they were the last person to touch the ball before it went out of bounds, they just pretend like it wasn't them to try to fool the ref into giving their team possession. Strangely enough, this is generally regarded as harmless "gamesmanship" even though it's essentially cheating, or at a minimum unsportsmanlike.
