Well, I say, by Satan’s Sweet Anus, Foghorn’s done got himself a new favorite band name!
Pie’s one of the things I came in to say. There are two exceptions: Pumpkin pie and chocolate cream pie.
Lobster. I hate the idea of sucking lobster meat out of a creepy tube (insert fellatio joke here). This from a guy who loves seafood.
Oysters. They’re fucking gross looking.
Steak. Can’t explain this one.
Other than that stuff I’m actually pretty open and I’m one of the least-picky eaters I know.
Those who can’t stand cheese would be in (abundant) company in China, where, I am told by my Chinese friends, not one person in a hundred will touch the stuff.
I’m so glad I like seafood - I once had a bit of an allergic reaction after a mixed seafood meal, and was terribly concerned that this was going to be a pattern. It wasn’t, thank Og. I don’t know how I would get along without bivalves.
Not many things I don’t like that I would like to like, but if I could stomach the weird german dishes my SO eats as a part of her heritage - like german potato salad and rinderwurst, for example - it would make life easier for her.
Cats, I like cats but I can’t eat a whole one. 
Wheat bread, rye bread and other dark breads. They are supposed to be better for you but no thanks, any white bread does the job in question better. Wonder Bread is better than the best loaf of rye bread ever made and I am generally a food snob.
