I hate jelly. Try PB and mayonnaise. Seriously. My Dad ate these when I was a kid and I thought it sounded disgusting. And then I tried it. I haven't made people try it since college, but all were more impressed with it than they expected to be.
Oooh, really hate the talking "Congratulations, you have won a free Nintendo Wii/I-pod" ads. Kinda sad to see those have creeped onto the forum.
