I shudder to think of the jokes he tells when he gets chocolate.
Although all good jokes should be funny on their own, we all know that many jokes become much funnier when told by certain people. For example, all dirty jokes become ten to twenty times funnier when told by really old people. Maybe it's because we don't expect old people to have raunchy senses of humor (despite overwhelming evidence that they were once randy youngsters), or maybe because we imagine them first learning the joke in a more innocent time. For example, I always imagine all old people learned their jokes in Rick's Cafe from Casablanca. In any case, YouTuber Geoff Fox took his 89-year-old dad out for ice cream, prompting Mr. Fox to regale the Internet with this classic dirty old man joke.
You can tell it's an old joke because the problem with the car involved actual mechanical parts and the mechanic didn't turn the penguin away by saying, "oh, I'm sorry, only a licensed computer scientist for this car company can diagnose your problem," a phrase which does not lend itself to double entendre.
