If you feel like the joke is going over your head, you’re most likely overthinking it. Farside comics are notoriously silly and simple. For the most famous example, check out the wiki article for “Cow Tools.” It should help put everything into perspective!
A note for anyone stumbling upon these comics for the first time: if you read too much into these, you’re going to walk away confused. If you don’t like that kind of humor, it probably just isn’t for you. I personally find them to be quaint and cozy, but it’s definitely not for everyone.
Hope everyone scrolls long enough to find the one that hits right though!
