Whilst camping in the UK a bit ago we had a rental "caravanette" as it was
called.  One night I tried to take a shower.  I assembled the plastic
shroud outside the camper, and with me on the inside of the plastic and the
wife in the camper to control the heat, she turned it on.  The hot water
created a draft from the floor out the top, the plastic got wet, and the
entire thing grabbed me like a long lost lover!  With my hands pined to my
sides I was helpless to move, and the wife was unable to turn the water off
as she was helpless with laughter.   I now know exactly what a sausage
feels like.
