clipcrop gave me a suggestion that didn't quite work but I changed his instructions a little and had fun.

Of course I was naked.
I put raw rice kernals into my socks and put them on in the kitchen, OUCH!
I walked to my bedroom and tied on a crotch rope
Then I stood in the shower and squatted down and clasped my hands under me
Finally I peed all over myself! I forgot to tell you I drank a lot of water about an hour earlier

This was FUN???
It hurt my feet, which really hurts, try it
I was embarassed that I peed on myself and the crotch rope. The rope really made a mess.
It was nice to be in the shower so that I could clean up afterwards
