One of the most indelible advertising slogans from my childhood - besides the kid fishing on the pier eating a sandwich and singing "O-S-C-A-R..." - is the "hey, get your chocolate out of my peanut butter!" refrain for Reese's Peanut Butter Cups. I've never been a huge chocolate fan, but for some reason, ever since I head that slogan and started tossing peanut butter cups into my mouth, I've been smitten with the combination of chocolate and peanut butter. A few years ago, I discovered a spectacular marriage of these two elements at The Brown Cow ice cream shop in Forest Park. Any other good ice cream combos you've seen around town?
