16. Flavored Tootsie Rolls
These things seem to only exist during Halloween or in your grandma's candy dish but, damn it, they offer the chance to do some great alchemy. Pop a vanilla and an orange in your mouth? Creamsicle. A lemon and a lime? Sprite candy. Eat them all at once? You're a crazy person, and we should hang out.
Skittles would be way higher on this list if we could forget that time we put a whole bag in our mouth and cut the insides of our cheeks on all the sugar shrapnel that exploded everywhere. On the other hand, getting Skittles directly into your bloodstream is kind of amazing.
Nerds are basically little sugar boogers with a slight hint of fruit flavor but they sadly don't come in flavor combo packs at Halloween. Dump random flavors in your mouth and hope for the best.
If they were embedded in a cookie or something, they might be No. 1, but M&Ms are still pretty great on their own. Especially if they're the peanut kind. Or the peanut butter kind. Or the pretzel kind... actually, why don't they make a little bag with all the different flavors inside? That would put it in contention for the top five. Take heed, Mars.
