45min time control, no move delay, and no extra time after "x" moves. Board 1 at a high school pre-season match. I had 2 min left and a drawn position. It wasn't obvious to everyone, but it was there. I offered a draw, he declined. We played. At 3 seconds left, I claimed "insufficient losing chances." We both look at the clock, and watch it tick from 1 to 0 seconds. He claims a win, I went to get a TD. Unfortunantyl, they were having a meeting, so I got the most junior TD. His first question: "what is insufficient losing chances?" I practically fell out of my chair. After explaining it and the rule, he stares at the board and states: "but you can't win, so you can't claim insufficient losing chances." I turn to him: "Yes and no, I can't win, but I can't lose." Eventually, he just gave me 5 minutes on my clock and said "prove it." 10 moves later my oponent came to his senses and took the draw. Regardless, I think I got away with something, but after that everyone has made me play on a delay clock, so that I can't pull something like that again.
