Some years back, I bought this video game (yes, I still play those) where you would go around and collect different types of weapons and armor. Now, I'd known for some time that gherkins are pickles, but I didn't really know how gherkin was spelled. So, when I found a type of armor called a "jerkin" (apparently some sort of padded leather suit) I thought "what...? Why is there pickle armor in this game?!" I was really embarrassed when my friend told me otherwise.
