It is implied that Patrick's hair was "activated" when he came into SpongeBob's house, but if this were the case, from the angle the camera shows, you should be able to see Patrick's hair. However, looking closely, Patrick's hair is absent. Notice, when he shows his hair, he didn't have to struggle to grow it.
When the formula is seen, look closely, the words don't make any sense.
The hair Patrick has only appears in this episode.
SpongeBob, Patrick, and Squidward were asked to do a band gig, but it never happened.
At the end of this episode, Squidward is still muscular; however, after this episode, Squidward's body is magically back to normal.
In this episode, Patrick just figured out where boogers came from, however in "The Battle of Bikini Bottom" he picked boogers out of his nose.
When SpongeBob is running past Squidward's house to tell Patrick about the band, SpongeBob's house isn't there.
When the Krabby Patty formula was opened up, all you could see were just random letters (but not words).
When SpongeBob, Patrick, and Squidward were asked to do a band gig, it never happened.
Patrick's hidden talent: growing hair strangely (even on the back of his head).
In the end, Plankton said that he couldn't escape from prison, but the bars were wide enough for him to squeeze out.
The name of the band was Plankton and the Krabby Patty Stealers.
SpongeBob: Hey Plankton, can our first song go like this? (Plays a disturbing, screeching noise) And then turn into one of those songs that go like this? (An even more disturbing sound is played)
Plankton: (Covering ears) Yes, perfect.
Patrick: I found out where boogers come from. (whispers in SpongeBob's ear)
SpongeBob: Ew, really?
Squidward: I have a lot of work to do before I am famous!
SpongeBob: Squidward, are you ready?
Squidward: I am ready!
SpongeBob: Patrick, are you ready?
Patrick: (plays drum with his belly)
SpongeBob: Plankton, are you ready? Plankton? (sees him holding a bottle with the formula in it) Plankton!
SpongeBob: (singing) Time to feed him! Time to feed him! Now it's Gary's feeding time!
Plankton: (angrily) Nope! (searches through SpongeBob's brain some more)
SpongeBob: (singing) Brush, brush, brush my teeth. Gently keep them clean.
SpongeBob: Oh, I wish I was grinding up the Krabby Patties.
That's what I really love to do.
Take a couple Boo-Ooh-Ooh!
And a pinch of Awoogah!
A teaspoon of *raspberry*
Then I mix some of this and put it over there,
as I write this song.
Mix in some...
Add a splash of wee...
(takes out giant knife)
And when I'm done, I chop up some
Oh. Oh-oh, Oh-oh...
Guard #2: He could be right under our noses! (camera goes to Police Officer #1's moustache; the moustache then jumps off of the guy's face, running away) Umm... Frank, where's your moustache?
Patrick: Can I get mine in pink? (after getting pink shirt) It looks like a tattoo.
Patrick: I play a mean belly. (drums "William Tell" on his belly)
(after getting his t-shirt)
SpongeBob: Plankton and the...Patty Stealers?
SpongeBob: Can Patrick join our band?
Plankton: Sure, whatever.
Plankton: Hey, it's my old guitar. I used to play it when I was in that band as a kid. Man, those were good times. (thinks about him being alone in a band) You know, I don't think I've had any good times.
SpongeBob: (gasps) I know what you're doing!
Plankton: What, me? I'm not trying to steal the Patty formula!
SpongeBob: You want me to... join your band!
Guard #1: He's too dangerous to let him around the other inmates.
Guard #2: Why, what'd he do, rob a bank?
Guard #1: Worse. He tried to steal the Krabby Patty formula.
Guard #2: Oh, okay...
Cop: Just keep your nose clean, kid.
Plankton: But I liked my old cell!
Cop #1: Then you're gonna love this one!
SpongeBob: There's no time to waste, Plankton. We've only got 22 years to practice before our next gig. A one and a two...
(Squidward plays the guitar)
Plankton: Oh, no! It's the cops! I can't let them see me.
Plankton: Why? Uh, cops are autograph hounds. Yeah, they're always after me.
SpongeBob: Mmm, that's tough. Don't worry, I'll hide you! (inhales Plankton into his nose)
Plankton: No, not this. (continues searching SpongeBob's brain)
SpongeBob: What's that?
Plankton: It's my... recording equipment! (laughs)
Patrick: I once searched for my innermost secrets. All I found was this. (pulls out his heart and holds it up)
SpongeBob: Is that what you mean, Plankton?
SpongeBob: Man, how'd you grow that so fast?
Patrick: Natural talent.
SpongeBob: Patrick! Patrick!
Patrick: SpongeBob! SpongeBob!
SpongeBob: Patrick, I've got big news!
Patrick: Me too! Me too!
SpongeBob: What's your news?
Patrick: I found out where boogers come from!
(Patrick whispers in SpongeBob's ear)
SpongeBob: Eew, really?
SpongeBob: Wait a minute! Was this band just a front so you could steal the Krabby Patty formula?
Plankton: What? No, I was in it for the music, man!
