Yep, I know a guy who is about 55 years old and has NEVER brushed his teeth, he gargles with mouthwash every day. His teeth are very nice. He also refuses to eat a hotdog on a hamburger roll, he'd starve to death first. He will not eat cheese of any kind. He will absolutely love a certain meal and eat it for years until he finds out that there is cheese in the recipe and never eat it again. This same guy will not pick out or wear a new pair of shoes, sneakers or boots, he makes his wife buy the footwear and she wears them around the house until the "factory germs" are out of them.
If that ain't weird, what the heck is?
