OK, I can probably beat you all with the longest list of things I don't like. I have no idea why I'm such a picky eater, but I yam what I yam.

I hate:
any and all seafood
coconut
mustard
honeydew/cantaloupe
nuts/seeds (one or two exceptions)
tomatoes (but I DO like ketchup)
celery
lettuce (unless drownding in salad dressing)
bell peppers
jalapenos and other spicy things
uncommon meat like veal, lamb, duck, etc...
cabbage and most leafy greens
asparagus
peas
grape flavored drinks/sodas
diet flavored drinks/sodas
grapefruit
pickles
tap water
I'm sure there's more that I can't think of at the moment, but you get the picture.
