This is the episode that aired as part of the "SpongeBob's House Party" special featuring clips in between of Patchy the Pirate and his house party. It's one of my favourite episodes of season 3.
Some funny quotes:
SpongeBob: Squidward, you made it!
Squidward: My cable's out. (Spongebob hides some wire cutters behind his back)
SpongeBob: Oh, uhh, sorry to hear about that.
Patrick: Kcirtap si eman ym o77eh. I don't get it.
Mr Krabs: No, you dumb bunny, it says, 'Hello, my name is Patrick'.
Patrick: (shakes Mr Krabs hand) Nice to meet you Patrick.
Mr Krabs: (laughs) Good one, Patrick! (both laugh)
Lady Fish: My card says, 'Discuss the philosophical nature of irony.' What does yours say?
Patrick: 'Nod politely'. (shown Mr Krabs and Plankton with cards)
SpongeBob: Well, it's about time. Ok, everyone, the last guest is about to arrive...22 minutes late! (opens up the door to a fish)
Fish: Hey, hey! (Spongebob folds his arms in a sort of anger. The fish laughs nervously as Spongebob walks into the party)
SpongeBob: Attention everyone. Attention please! Now that we're all here, I officially declare the party switch to be in the 'on' position! (silence) (everyone claps silently) As soon as I get back from the coat room, we'll have a rundown of tonight's schedule. Try not to have too much fun without me! (laughs as he walks into a room with a sign that reads 'Coat Check'.) Seriously. (closes door)
