There was a sprite commercial for "Sun Fizz" a few years back that was probably the funniest I've ever seen. It shows a mom coming in to serve her kids up some "Sun Fizz" and as she opens the bottle the little animated Sun Fizz character pops up and says some [censored] like "Oh hey kids! Sun Fizz is delicious."
The kids start screaming like they don't know where the hell this thing came from and the mom yells, "Oh my god! Kids, run!!!" and the whole time the Sun Fizz guy is screaming something like, "Wait kids! I'm full of vitamins!" as he's chasing after them. It's absolutely hilarious.
I googled it but couldn't find suitable video outside of adcritic. If anyone finds it...
please link to it.
EDIT: OMG! I FOUND IT:
