I saw this ad a few months ago while babysitting for my niece. It's truly a ridiculous ad, and it reminds me of lots of silly things, the first of which is Cheech & Chong's Nice Dreams. Lost? I will refresh your memory.
In this ad, Fred Flintstone and Barney Rubble are at Mr. Slate's quarry, and they're eating Fruity Pebbles. Well, apparently they have 64 flavors now, and after Fred takes a bite, he says: "It rocks your whole mouth!" Then we see a picture of an escalator taking the cereal up to his brain from his mouth. (So I guess his brain is part of his mouth? No wonder he's such a lunk-head.) Oh, but just then, Mr. Slate catches them slacking off (I didn't know Barney worked there too. Oh well, cheat when you have to, I guess.), and he yells at them to get back to work, whereupon he spies a bowl of Fruity Pebbles they have left behind as a practical joke. You see, it's a joke because that bowl doesn't have 64 flavors, so it turns Mr. Slate into a crocodile (?), just like the marijuana did to people in Nice Dreams. So, are we to infer that Fred and Barney intentionally put tainted marijuana into the bowl for Mr. Slate to eat? And isn't that a felony? (Maybe not in the stone age.)
Then there's another issue with this ad I have to take. You see, this spot infers that if you eat the non-64-flavored cereal, you'll turn into a dinosaur, or a crocodile, or whatever it is. But kids would love to be able to turn into such things! So now they'll all want to get the old version of the cereal on eBay, and when it doesn't transform them into a monster so they can go on a rampage, they'll be able to sue for false advertising. (The people who made this spot either don't have kids, or they don't remember what it was like to be a kid.)
Here's the crocodile converting cereal commercial:
