When I was younger, I thought the word vinegar was the same as the word vagina, and in year 5, we had a TV crew come to our school, to do a documentary on school dinners, and I said into the microphone, which was turned up quite loud 'well I usually have ketchup or mayonnaise on my fries, but my older brother, in high school, prefers vagina with his'. Needless to say, that part was obviously deleted.
