toilet seat polio

When one spends more time than necessary, clearly violating the fifteen minute maximum rule for being on the toilet, blood flow to the legs is reduced causing numbness. The legs and feet then fall asleep. When finished, walking now becomes quite challenging. The steps taken by the sufferer resemble those taken of people with polio.

Dave, why are you walking so funny?

Spent too long in the crapper,now I've got toilet seat polio.
