This bothered me so much that I almost quit watching the show... During that tennis instructor episode ( the one about the wife's tennis pro who's so good looking that "every" woman wants him), Bob is in his dentist pals chair for a cleaning. Well at one point the dentist is wiping the plaque from Bob's teeth, from the tool directly onto the cape that Bob has on. Directly on the cape! Not on a napkin or anything else. Horrid, nasty tooth muck on a cape that's supposed to be used for a dozen other patients. How did they overlook that?

They probably wash them. :)

They probably wash them. :)

after each patient? imagine a woman with shoulder length hair... the ends of her hair brushing against and picking up the plaque of the previous patients LOL.
I just can't see how they overlooked that. That said, I am glad I didn't quit watching. I love the show.
