Did a soph/jv DH last night. After the game the varsity guys were just finishing up their pregame, and as they went to grab their stuff to head out, one realized he had no whistles. He'd had his daughter clean them in peroxide, and she hadn't put them back in his bag.
Whoops!
Lucky for him both my partner and I had unused spares to offer.
I also keep an emergeny spare looped over my rear-view mirror. Paranoia keeps me alive
