Squidward has made a very good soufflé, but SpongeBob and Patrick's constant laughing distracts him from enjoying it. Squidward sees that they're having a private conversation with bubbles. They whisper a message into the bubble wand instead of blowing into it, and when the bubble pops, the message can be heard.
Annoyed by that, Squidward makes bubbles of his own, imitating SpongeBob and Patrick, but insulting them both. Thinking the bubbles are from them other, SpongeBob and Patrick become angry and get into a fight, eventually declaring that they are no longer friends. Squidward comes outside and eats his soufflé while laughing, but in doing so, he chokes on the fork. Patrick saves his life by performing CPR on him (which is basically blowing him up and as the air comes out, the fork can be seen spluttering in between his lips) and becomes Squidward's friend. Inside Squidward's house Patrick falls asleep while Squidward plays a composition called "Solitude in E Minor" on his clarinet, and Squidward pulls him outside. While doing this, he sprains his back, and SpongeBob sees this as an opportunity to help him. He bumps into Squidward's back and thus becomes Squidward's friend.
Inside, SpongeBob plays a song (badly) for Squidward on his Double Bass (which he thinks is a bassinet) and when Patrick appears in the window and interrupts the song, SpongeBob destroys the instrument in a fit of rage, and Squidward kicks him out. Squidward then tries to take a bath but Patrick is in the tub. SpongeBob appears in the window and sees this, and he and Patrick begin arguing again, driving Squidward crazy.
Squidward decides to invite Patrick and SpongeBob to a dinner party (without telling either of them that the other is coming) in order to repair their friendship. When they arrive, they are still mad at each other. Squidward tries to get them back together, but the situation devolves into a competition to see who can drink the most soda and thus become Squidward's best friend. Squidward runs out of soda and leaves to get some more. While he is gone, SpongeBob and Patrick, who have become literally inflated from all the soda, begin to hiccup small bubbles that make a burping sound when they burst. They find this amusing and become friends again, but they create so many bubbles that Squidward's house explodes. Squidward orders them out and slams the door. A bubble pops over the door, which then falls over on Squidward, moaning "Oh, my back" as the episode ends.
Squidward jumps toward his cake, which is strange because he always yells at SpongeBob for being hyperactive.

When Squidward goes into the bathroom and screams and the scene cuts to Patrick in Squidward's bath has become an internet fad called Guess who's in Squidward's bath which has a scary or funny face replacing Patrick's face.
When SpongeBob asks Squidward for an 'A', Squidward actually plays him a B flat or a C written for the clarinet.
When Squidward uses his keys to unlock the door, there was an explosion. Then Squidward bites his hand and opens the door, already unlocked. The explosion may have broke the lock on the door, though.
When Patrick falls asleep when Squidward plays an E minor, it has an internet fad call Patrick thinks [song, singer or band]is boring where a scene of a song will play and the scene where Patrick is asleep then plays.
SpongeBob said he was playing bassinet for years. However, a bassinet is a type of cradle. SpongeBob was actually playing a double bass, or a contrabass.
Squidward could have just told SpongeBob and Patrick the truth about who sent them the mean bubble messages to get them to stop bothering him.
When SpongeBob is playing the "bassinet" at Squidward's house, there are only 3 strings instead of 4. However, when SpongeBob smashes the instrument, one can see that the bassinet now has 4 strings.
As Patrick and Squidward are walking into Squidward's house, his back window has no glass.

It is almost impossible for Squidward to make bubbles out of the purple soap of his cake, since he held it and blew it with a fork and the bubbles would probably pop before it gets to Spongebob or Patrick.
Spongebob rips his clothes off while launching himself to Squidward, but when he reappears he is wearing his clothes again.
