This is the worst episode ever for SpongeBob and was a total letdown.
First, they advertise on this episode. They even had a 24-hour long marathon for this episode. And on airing night, it was a DISASTER. It was so short (10 minutes) that is sucked.
First off, SpongeBob wakes up and sings that it will be "the best day ever". That best day ever is actually what he normally does (jellyfishing, working at The Krusty Krab, karate chopping with Sandy). The only addition is Squidward's concert. Why did Squidward have his own concert? He's not even good at his clarinet! It starts off that he goes off to the Krusty Krab to go to work but the nematodes from "Home Sweet Pineapple" have invaded the restaurant. So, Mr. Krabs can't get into the restaurant. And then, SpongeBob has to play a note of his nose flute to calm them down. So that ruined SpongeBob's day at the Krusty Krab. And then he goes jellyfishing with Patrick but he broke his net. SpongeBob decides to give Patrick his jellyfishing net. Again, that ruined SpongeBob's day jellyfishing, so he goes to Sandy's treedome to karate chop. But Sandy had a crack that leaked in her treedome. So SpongeBob has to lift his karate chopping glove into the leak. Again, it ruined SpongeBob's day karate chopping. So he goes to Squidward's concert but the ticket guy won't let him in. So SpongeBob does a lot of stuff to get in and then the ticket gut realizes that it is SpongeBob. So the ticket guy takes SpongeBob to his VIP seat. And then Squidward plays. But since SpongeBob realizes that it has not been "the best day ever". So he makes a musical called "The Best Day Ever" and the episode ends. The worst episode of SpongeBob EVER!
Final Score: Z-!!! (Real grade is F)
