Oh goodness, this episode is so boring.
How can you mess up an episode centering around the elderly, there are tons, countless amounts of opportunities for jokes at elders' expense? So I was afraid that this episode was going to be terrible, as the title card sounded terrible, and...it's not as bad as I thought it would be. I'll get this off my chest, it's definitely not a good episode, but it definitely restrains itself from being as atrocious as it could've been.
The plot is very original, which I guess is the highlight of the episode. But even then, the plot isn't even that entertaining, it mostly centers around different scenarios the elderly are placed into, in order to regain a childhood spirit. Heck, the way I described it sounds better than the way this episode was executed! The premise of the episode in which Patrick just ages...out of nowhere...
Okay, there is a clever way Patrick ages in this episode (He's been in the pool so long, he becomes extremely wrinkly), but...this episode...is so confusing with how this age thing works. Patrick is full of energy, and is only physically wrinkly up until he starts doing elderly things. The whole reason he joined the elderly group is because of icecream, he eats the icecream, gets a brain freeze. Does this ruin his memory, and makes him think he's an actual old man? No! He seems perfectly fine afterwards! When his brain catches on fire and he eats it ("Funny" visual humor), without a brain to supply him with memory, does he automatically assume he's an elderly man? No! He gets wrapped up in old people activities because plot says so, and doesn't recognize SpongeBob.
Okay, so it's a gradual progression into Patrick's brainwashing, I can respect tha-He recognizes SpongeBob a handful of seconds after not recognizing SpongeBob. So...how does that work? How is Patrick brainwashed, yet easily phased back into knowing who he is? And even then, if he was so full of life in one scene, why did he become all sluggish all of a sudden. I do have a pretty clear idea of what this episode is trying to get at, Patrick becomes so engaged in these activities, he essentially loses track of who he is. But the episode does a pretty sloppy effort at trying to make it clear to the casual audience member. Okay, so we know how Patrick ages, through being soaked in water for his physical aging, and through his gradual shift into the elder state-of-mind through participating in "fun" activities at the Shady Shoals. But how does SpongeBob turn into an elder out of nowhere!? He runs into a ball pit, and saves Patrick from drowning, okay...
But when he comes out, he turns into an old man! Is it a disease!? SpongeBob doesn't even do elderly things like Patrick does, he just out of nowhere becomes physically frail to benefit the plot! And instantly in the following scene, he has the power to revert back to normal. There was at least a creative way for Patrick to de-age, but SpongeBob, we don't even see any steam pour out of his pores when Patrick puts a blanket over him. It just doesn't make sense, how does SpongeBob age and de-age at will? It's only present to progress the plot, yet it's so forced in!
As for the comedy, this episode has humor as stale as the elderly fish that appear in this episode! Most of your jokes are run-of-the-mill, forgettable visual gags that're only appealing for maybe a second or two, but the absolute WORST part of the episode is the "Marco" running gag. It's so painfully corny, a literal joke that would only make those 3 and under laugh their brains out. I actually really enjoy the Marco character. I think his voice actor did an amazing job voicing him, putting lots of expression and emotion into his performance making him an entertaining and enjoyable character. But the joke he's attached to is just awful. There are a few really funny jokes in this episode, particularly the gruesome closeups of some of the elderly fish, and Patrick's "fun" activities as an old person that're demonstrated to SpongeBob were pretty amusing. Overall, this episode has some hit-or-miss.
As for the rest of the characters, well, they're not really that bad. Patrick and SpongeBob are alright, I guess. Patrick is fairly annoying at the beginning of this episode, but he really mellows out once he drags on as an elder. Really, they're tolerable when their actions aren't being damaged by this episode's plot holes.
Overall, it's a Bad Episode. I give it a 4/10
