Nah, just happen to lose a grip on the Nozzle while putting out water at 100+ PSI full open accidently washing down Officer Doughnut.
Yeah, or "Oh, that was your cruiser with the window down? Gee, sorry, I slipped and bumped the valve bar on the nozzle as we were hauling the charged hose by and...well, that sucker sure does put out a lot of water in a hurry, doesn't it?"
