Boy, wouldn't it be "interesting" to find yourself in that little bathroom in the back of a charter bus, just as the bus comes to an abrupt stop? You'd go falling to the floor with your pants down around your ankles seeing as how these things have just enough room for a small child to use them, you're chancing of landing face-down in the middle of the aisle would seem pretty good.
Now, if you want to prevent that I'm sure you could always just prop your feet up on the wall, grab ahold of the grab bars and hold the door shut if needed. That should keep you pretty well planted on the pot. If that doesn't help then you're just better off going ahead and peeing on the floor sense you're going to be there anyways.
For those of us who are capable of standing up and doing our thing all we really need to do is lean up against the wall to start with and hope your aim is as good as it should after this many years of shooting it into the jon.
The problem there is if you stil lose it and fall through the door. Then you'd be totally exposed to everyone and you might even fling a little bit down a ways, and we all know that would just be horrible. You'd be lying on your back with your 'him' sticking out and all you can do is hope nobody looked to see what the loud noise was and where that little bit of 'water' came from.
Just something that came up when I went out to eat with Sarah and her family tonight.
Capt. over and out!
