Sort of a SRI.

The scene: Out for a black tie charity fundraiser with a remote control vibrating egg inside me snatch -- remote control for this egg was in Dragon's pocket.

In the course of the evening, i was getting off a barstool (i'm 4'11 so it is a bit of a gap to the floor) and suddenly the egg starts up at maximum speed. Foot slips off the rung of the barstool, i crumple to the floor in a quivering heap. Hit my head on the bar rail requiring 6 stitches and breaking my collar bone. There was also damage to my reputation (and my pride), since i had to overcome the notion that i got falling down drunk in public.

No injury involved, but holding a small subbie face down on a memory foam mattress can lead to some unintentional breath play.
