Dancers: Thanks for taking the heat and asking the question. I had no idea what a Gerni was. I do know what a Bidet is and I've lived in two homes with one. It's a small water feature with a cute little fountain in the middle that you can turn on, contemplate and enjoy while you sit on the toilet that is usually placed next to it. You just have to be careful not to turn it on too far or you have to get a towel and dry the ceiling. (to SX2002--it's a joke! )
OK, so "they have been used to clean things all over the world" but the question in point is what kind of job are they doing when you need to clean your rear end, huh?? . . .
