SpongeBob SquarePants, Season 1

SpongeBob:
Squidward! Hey, Squidward! Squidward! Squidward-ier! [Squidward peeks out his window] Squidward! Look at my new pet.

Squidward:
That's no pet, that's a wild animal.

SpongeBob:
No, he isn't. Watch this. [throws a stick so the jellyfish returns it. SpongeBob is holding up 3 fingers] How many fingers am I holding up?

Jellyfish:
[humming] 1, 2, 3.

SpongeBob:
Play dead! [jellyfish is buried underground with a tomb that says "R.I.P.". He pops up]

Squidward:
I wouldn't let that thing into my house even if it was potty trained! [the jellyfish, still on the rope, is on a toilet reading a newspaper as he hums casually] ...I didn't need to see that.

SpongeBob:
Well, we're going to my house to have a little fun.

Squidward:
How can you possibly have fun with a jellyfish?

[they proceed to show exactly how, as they then launch into a loud, intense rave in SpongeBob's house]
