I used to think that plumbers were men who had to live inside the toilet and sweep all of the...wastes...out. I was always afraid one of them would accidentially climb out of the toilet while I was using it. To top it all off, my dad had a friend who was a plumber and I always asked him what it was like inside the toilet. He probably thought I was insane. Which I was. But I'm fine now.
