I'd actually never seen these hilarious microwave style Jiffy Pop bowls before! The ad is older than I am [just by a year, lol] but I grew up only eating the stove-top version of Jiffy Pop.
This is a classic from my youth, circa 1969. A shorter, 30 minute version is also available on YouTube, but this is the one I remember. All the people in this ad are forever engrained in my memory.
