Wonderful World of Tupperware (1959)
This short starts out with typical footage of Tupperware being made. Lots of perfect riff fodder. THEN, it shifts into pure "WTF" and then some. I swear you'll want to take drugs for this part to make sense. Seriously, Rifftrax guys, you'll love and hate this short! It's too "What the Hell" times 9000!
Bridget and Mary Jo just riffed this one, and it’s available here: https://www.rifftrax.com/wonderful-world-of-tupperware
