Jeri, your story reminds me of early days with Lady McMoo. I was fast asleep at about 4.30am when mournful cries came from the toilet area. Sure enough, not being any kind of gentleman, during my perambulations earlier in the night I had failed to put the toilet seat down. When I arrived bleary eyed a few moments later, there she was, securely and firmly wedged IN the toilet. Pulling hard merely caused further distress and, if I remember correctly, it was the handy proximity of a can of WD40 that eventually saved the day. (Must remember to add that to the WD40 thread).
By the way, nearly every toilet in Switzerland seems to have that curious little poop inspection ledge you referred to!
