So there is a sign that says 'Please keep the lid shut to help with ventilation and odor' and I think 'how nice!'. So I open the lid, drop my drawers and sit my naked white butt down on the lid.
Now, there is a myth they busted on Mythbusters that talks about someone flushing an airplane toilet and the suction keeping the person stuck on the toliet. That immediately went through my mind as I realized that the ventilation the sign was speaking of wasn't in the room I was in but actually from beneath in the big hole containg the motherload of crap. The next effect was a suction effect that pulled air down the toilet from around my butt and croch that wasn't all together unpleasant but very VERY weird.
