Picture this: You're in a public restroom stall and it's literally wall-to-wall shit stains.

Do you A) try another stall, B) leave the restroom altogether because God only knows what else goes on in there, or C) pull out a carrying case containing a nylon toilet seat cover, do the deed, and then place the cover back in its case after lightly rinsing it in the sink of the same restroom containing a shit-stained toilet stall.

If you answered C, congrats: You are the proud owner of the Potty Pax.

Also: You have dysentery.
