Back on the subject of the episode, I don't know if this was brought up in the episode comments (And there are a lot of comments on the episode now) but I was amused at the readers' reactions to TitaniumTeeth's post. Not so much the post itself, but the fact that you guys expressed confusion over his use of the word "caries", which is in fact perfectly cromulent.
The only reason I know this is that I have high-strength prescription toothpaste which is described as being for "Treatment and prevention of dental caries". It's just another word for cavities or tooth decay, really.
