True, though I doubt every single person on these shows has medical bathroom issues.

Then again, they might. There sure are a lot of biracial and gay couples, maybe the people putting together these shows also pick a lot of couples with at least one not-visibly-disabled partner.

Edit: Not that, obviously, there's anything the matter with biracial and/or gay couples, indeed, it's better than everybody being the same that you so often see. It's just noticeable, and a little disproportionate. I'm not complaining, at any rate.
