Q: What’s worse than finding a worm in your apple?
A: Finding half a worm!
Explanation: Imagine biting into an apple and finding a worm. Yes, that is a very unpleasant thought because your apple is most likely not in very good condition.
Now, imagine biting into an apple and finding only half of a worm. That means that the other half is in your mouth! Yuck!!
This joke is funny because it sets up the expectation for something bigger, worse than a worm, and then surprises us with less than a worm, only half of a worm.
So, why are there so many types of apples?
