Funny that Europeans used bidets to clean there arses long before they even considered picking up a toothbrush!

My guess is that the Japanese already have a toilet seat that will do both -- work like a bidet and brush your teeth -- and massage your bottom, too. I had to carefully look at what I was pushing on a toilet in a Japanese hotel, not because the labels were in Japanese but because there were about a half-dozen of them and I didn't want to activate the bidet function.
