California Raisins
Just a couple of the countless ads from the 80s.

Cheetos
"The Lie Detector"

Cheez-It
"They just... cheese it." A couple of ads I've always found oddly cute.

Chobani
"The Wonderful World of Less"

Dannon Yogurt
French maid

Diamond Nuts
First is an amusing ad for Emerald Nuts, in which a dad engages in some bad parenting. (Emerald is a subsidiary of Diamond.) Then I had a playlist with several amusing ads for recipes that use Diamond nuts, but those videos were removed from YouTube and I couldn't find replacements, unfortunately.

Doritos
"Crystal ball", then "time machine", then "The Cool Ranch" (feat. Lil Nas X and Sam Elliott).

Goldfish Crackers
There have been a ton of these ads (I could definitely give them their own page), but for now I think I'll just post this one, which I find the most memorable of the campaign.

Hostess
In the 90s, there was a series of ridiculous ads with the tagline "Hey, where's the cream filling?" This is one I usually think of each year during Shark Week.

Oreo
Twist on it.

Pepperidge Farm
I must've seen other ads for their cookies over the years, most of which I probably wouldn't remember. Which is a shame. But here's a more recent one that's really funny.

Planters
This ad is from 2010, and Mr. Peanut is voiced by Robert Downey, Jr. In 2013 I saw the ad again, but it seems the voice has changed... though it's hard to tell, it seems like the new guy's trying to sound like Downey. I dunno. Anyway, there've been plenty of other ads over the years, both before and since Downey's tenure in the ads, but for now this is the only one I can think of, that I care about at all.

Quaker
Quaker Up - "Lake", because imagination is awesome. (see also breakfast)

Wheat Thins
An ad for Spicy Buffalo Wheat Thins, with a double twist ending that I find hilarious.

Wonderful Halos
Old Witch; dolls/creepy twins; circus

Yoplait
No doubt I've seen a number of Yoplait ads over the years that I'd include here if I could specifically remember them. Or find them online. (I'm sure in the 90s they used to do ads with a motto in French.) But right now I can just remember a couple of recent ones. From 2013, there's "swap one a week" (which has disappeared) and from 2014 there's "spoons."
