I would vote "no"... but I had to go with Joe Zelenka.
FYI: Joe Zelenka (aka Joe Z) is the long snapper and a reserve tight end for the Jacksonville Jaguars and a very funny guy. He even has a fan club: http://www.angelfire.com/fl5/joeyz/
But I digress...
Reese's cups can't be a candy bar because they are not in bar form! They are candy rounds. If the made them into the shape of a bar they would then qualify as a candy bar.
No, because they're not a bar. Reese's are their own unique thing, and I don't even feel a need to categorize them, beyond acknowledging that they are the world's most perfect candy.
