Hate to resurrect this, but someone just brought me up a box of Bott's every flavor beans. I gotta say, they are amazingly accurate. At least they are with the one's I've gotten the nerve to try. We've got...
Banana, Black Pepper, Blueberry, Booger, Bubble Gum, Cherry, Cinnamon, Dirt, Ear Wax, Grape Jelly, Grass, Green Apple, Lemon Drop, Toasted Marshmallow, Buttered Popcorn, Sardine, Spinach, Tutti Fruitti, Vomit, and Watermelon.

So far I've tried (of the weird ones):
Black Pepper
Dirt
Grass
Sardine
Spinach

I just don't think I can handle Booger, Ear Wax, ir especially Vomit. Especially if they're as lifelike as the rest. -=shudder=-
