We have a crackhead Math teacher, Mrs. Bush, who lives by a dumpster (nice) where Frito-Lay dumps the surplus of shit that isn't sold or has gone bad. She brings this stuff into us, claiming that it's safe and fine, and "It was boxed up and sealed. There's nothing wrong with it," regardless of the fact that it's stale.
She is a purple woman.
So, today, she brought in three or four boxes of Salt and Vinegar chips (which are nasty, but we should be grateful; however, we're not). We, rather than paying attention to the purple lady, had a very in-depth conversation on the redundancy of "Salt and" in the name of these chips.
So, my question, friends, is if potato chips already have salt on them, why aren't Salt and Vinegar chips just called Vinegar chips? Is the added "Salt" necessary?
