Original Moose Tracks is my favorite.

Alternatively vanilla and then I cover it with a wide variety of my own toppings and a liberal amount of syrup. Ice cream is the only thing in the world I get food-geeky over. I will spend a half hour planning out the perfect bowl of ice cream with the perfect kinds of toppings and syrups and making it; with any other food it's either fast food or gets tossed in the microwave.
