When i used to work at Disneyland in parades, a few of us used to top shelf the bathrooms of any party that we went to that wasn't put on by the parade department.
In case you don't know, top shelfing is taking a shit in the top part of the toilet instead of the bowl. when you flush, well, lets just say, it's not pleasant...
I don't see what the big deal is either Marketsmart.... LOL
