I played on a Navy ship, does that count?

Anfunybstory, while playing during church service the weather was really bad, and i decided to play on top of midi files (over 15 years ago) on my GEM WX2..

Suddenly the ship made a bad unexpected move and i had to grab the keyboard with both my hands to prevent it from crashing on the floor, several crewmembers where less lucky and hit the ground. When they recoverded they started bursting as i stood there with my keyboard in both hands while the music played on. Now that was embarrasing for me and hilarious for the rest of the crew.
