What do you call a fruit that's always worried?

The humor in this food-themed joke springs from a delightful bit of wordplay, specifically a pun. The setup cleverly leads you to think about a fruit (Review), then twists your expectation by using a word that sounds almost identical to "pear" but carries a completely different meaning: "paranoid." It's a classic linguistic trick that makes us chuckle by forcing our brains to make a silly connection between a juicy snack and a state of mind.

To be "paranoid" means to be excessively suspicious or worried, often imagining threats that aren't really there. So, the image of a pear constantly glancing over its shoulder, fretting about being picked, bruised, or perhaps turned into a compote, is inherently absurd and amusing. While real pears are thankfully free from such anxieties, this joke gives the humble fruit a surprisingly human, and hilariously high-strung, personality, proving that even produce can be the star of a good, clean pun.
