This reminds me of mother launching my father off the waterbed(original style). My baby brother and I only ran to the door because of my father's frantic scream of Noooo! What we saw was mother coming from mid air landing on the bed and father going up in the air,over the side of the bed and into the wall. The direct result of a 5ft 9in 155 lbs female running across the room and jumping on the waterbed. Who needs Monty Python with parents like that?
