Can you be disqualified for a medical condition?

  What bodily functions are technically illegal in tournaments?  Let's say you show up for a tournament wearing a diaper with paperwork detailing a medical condition such as bowel incontinence.  You then claim that back pain is making it difficult for you to get in and out of your chair.  Can you justify staying at the table as a potential distraction to your opponent?  Is it actually in the USCF or FIDE rulebook or is it up to individual clubs?  Would there be concerns that the individual might claim discrimination afterwards if disqualified.

  In college, a bunch of us once got really drunk and staggered down to the bar in diapers because they had a special that at a certain time you could get free drinks until you left the bar to go the bathroom.  They eventually kicked us out because it was kind of hard for us to claim that we all suffered from incontinence.  We tried to claim we were members of a support group for sufferers of the condition, except they threw us out anyhow.  It never occurred to us to conceal the diapers under clothing, so that might have changed things.

Having tits should qualify most females.

Nigel Short's in depth peer reviewed scientific analysis shows that females are inferior at chess, but superior at cooking over a stove.
