SpongeBob SquarePants is one of the most instantly recognizable fictional characters in existence. His show has been on the air forever and entertained multiple generations of kids. It's even still entertaining to adults. The show has sneakily put in some dirty jokes you may have missed. Couple that with the memes it's produced, this is the show that just keeps on giving.
Part of the secret to having a show with such longevity is having an amazing supporting cast. As lovable as SpongeBob is, he can't carry the load all by himself. He has countless side characters that kept us laughing along the way.
You see this character talking to Mr. Krabs? His name is Old Man Jenkins. This isn't an alternate reality or timeline, it's simply a completely different-looking character with the same name. Confused? Just you wait.
Turns out, this is the real Old Man Jenkins. We weren't told what the deal is with all the other ones. But for the purposes of keeping your head canon straight, this tattered fella is the genuine article.
This has rocked many fans of the show. The guy in the picture here is the Old Man Jenkins we've all grown to accept. Do we have to readjust our entire way of viewing the series now? What next? Is Patrick not the real Patrick?
My advice is to just do your best to forget this. Remember when The Simpsons tried telling us Principal Skinner wasn't the real Skinner? We don't need another fiasco like that. Denial isn't often healthy, but when a show tries to sneakily replace your favorite characters the best course of action is to just ignore it and pretend everything is fine.
