TOD:
I like everything on John G.'s list.
My favorite is Baskin Robbins' Peanut Butter and Chocolate. I also love their Jamoca Almond Fudge.
Other favorites are:
Ben and Jerry's Chubby Hubby
Ben and Jerry's New York Super Fudge Chunk
And for Bruce, I thought I'd mention again that Trader Joe's has a cherry chocolate chip that's out of the this world. It's soy ice cream, but still extremely good.
What's the first ice cream flavor I ever had? How could I know that!? - I was probably three years old!
