Slightly a non sequitur. "Ketchup'ing" and pickling are effectively processes, but an actual pickle (not to be confused with "pickled") is vastly known to be a pickled cucumber. In my mind, I'd imagine if I were to ask 100 strangers if pickles were a naturally occurring vegetable, I'd wholly expect 100 people to tell me no. If one person said yes, I'd be shocked. If two people said yes, I'd post in this Escapist forum's thread. If three people said yes, I'd take a vow of silence, and never speak to another human being again for fear of "stupid" being infectious.
In fairness, this is coming from a man who, in his early preadolescences, thought that people's race wasn't determined by the parents, i.e.: two black people could have a Chinese baby, or two white people could have a black baby, etc. I thought race was like the coats of puppies in a single litter, all unique and fairly random. It was a pure and innocent belief, but one immediately dispelled by the time I was 8 years old when I was able to rationalize that most of my friends looked like their parents, and the idea of coincidence went out the window. This dude made it into his FIFTIES literally believing there were "pickle plants" out there somewhere. How did he not even accidentally find out the reality in over 50 years?
