Kraut juice: When Circus Peanuts aren’t enough
Dear Cecil:

At the risk of dragging out an already idiotic discussion (Circus Peanuts suck, period), I just wanted to provide reader Rob Atkinson with some interesting information. A few years back, I worked in a grocery store as a night stocker. A fellow night stocker, we’ll call him “Wayne,” started a stupid morning ritual of trying some bizarre new product at the end of each shift. One morning, his choice was a fine can of kraut juice. We weren’t sure if you were supposed to drink it by itself or what, but the packaging showed a mouthwatering WINE glass full of the green sludge.

Anyway, Wayne popped the cap open and took a big swig. He then began gagging and spitting out as much as he could. His first words after tasting the kraut juice were, “How can this be a marketable product!?!”

After calming down and quelling the desperate attempts of his stomach to return to sender, Wayne sat down, looked at the can, and then chugged the rest of it. After he nearly vomited once again we asked him why he did it. With a face nearly as green as the juice, he replied, “Well, I didn’t want to waste it.”
