There's an urban legend about animators at Pixar pranking Listerine executives while making a commercial. They filled one of the bottles with apple juice and made $20 bets to drink it. Supposedly one of the reps watching it being chugged went running for the bathroom to throw up.
I didn't even know this existed until a few years ago. The original version isn't sold in my country, even though there are like 10 different varieties of Listerine available in stores.
