Most favorite is a tossup. Peanut Butter Snickers, Take 5, Whatchamacallit, and Butterfinger I can all go for at any time.
Least favorite is anything solid chocolate. Anything from Hershey's to the really good stuff (for example, the stuff I got from a high end shop in Paris), if it doesn't have some sort of flavoring besides chocolate, I hate it.
Also, anything with chocolate chips. Disgusting. /flamesuit
