We just credited Gobblestix with some excellent pun work, but the makers of this snack food did even better. The play on words based around 'pop quiz' is extremely clever. We could have done without the zany misspelling, but it is what it is.
The flipside of this being a great pun is that it was a lousy idea for a snack. You didn't know what flavor of popcorn you'd bought until you popped it open and ate it - that was the 'quiz' aspect of the name.
