Jesus Sara! What do these people think bathrooms are for? Or to use the real word, toilet? Think people hold tea parties in them? Sewing circles? Discussion groups? You walk into a toilet, someone's using it, what the eff yoo see kay do you expect to be going on? Deep sea exploration? Magic tricks? Animal husbandry? (I'm specifically thinking of the Batlord here!)
Mind you, as long as that's going on in a toilet that's ok. It's when you have like Mr. Burns asking Homer, well did you find the restroom all right? And Homer looking shiftily around and saying, errr.. yeah....
Then you have a problem!
