Demolition Doofus wasn't on my bottom 15 list, but I'd definitely put in my bottom 50. I can safely say that in Demolition Doofus, ESH. SpongeBob came across as incredibly insensitive towards deflated Mrs. Puff, and Mrs. Puff took her rage way too far. The demolition derby was a novel idea, but it was ruined by Mrs. Puff's bloodlust.
Trenchbillies almost missed my bottom 15. Such an unfunny drag to get through. The character designs were hideous, 90% of the humor derives from tired hillbilly stereotypes, and the story just meanders about. I would safely say that this episode has more filler than low-quality pet food.
A SquarePants Family Vacation can be summed up in two words: painfully boring. Yeah, the road song was cool and all, but the whole episode is a nothingburger until the gift shop scene. It's a shame, because this episode had a lot of promise; the idea of SpongeBob and his parents taking a vacation sounded really interesting, but nope, we instead got a snorefest of a special.
Slide Whistle Stooges is mid-tier in my mind. Yeah, the sound of the slide whistles gets tiresome after a while, but I don't mind them all that much. Aside from the ending and the hypocritical Bikini Bottomites, it's hard for me to find any noteworthy flaws, but at the same time, it's also hard for me to find any laugh out loud moments. SWS is watchable, but not very memorable
