First time I ever saw it on a menu (at a '50s style diner) I shuddered at the thought. The waitress asked if I liked peanut butter, I told her I LOVE peanut butter. She said "Try the burger - if you don't like it, I'll give you anything on the menu for free".
Serious - if you like burgers and you like peanut butter, you don't know what you're missing if you haven't tried it. Do it now.
