Peanut butter and jelly, pb and pickles, pb on an apple or banana or carrot, pb swirled into vanilla ice cream or oatmeal... all good.
Peanut butter on a hamburger and a few of the other combos you've all mentioned... I'm getting queasy just reading about them.
Oh, and just for the record, the best pb in the world is the kind with no added sugar or salt. Just plain, naked peanuts. Preferably chunky.
