What do you call a disrespectful reindeer?

The joke “What do you call Santa’s most impolite reindeer? Rude-olf” is a play on words that hinges on the name of one of Santa’s most famous reindeer, Rudolph. The humor arises from the pun created by combining “rude,” which means impolite or ill-mannered, with the name “Rudolph.” By doing so, the joke creates a fictional reindeer named “Rude-olf,” suggesting that he is the most impolite of all the reindeer.
