2 Trying to burn Gary with a flamethrower (Pet Sitter Pat)
Pretty much everything he does to Gary in this episode is down right infuriating he even literally tries to murder Gary with a flamethrower.
3 Selfishly refusing to give SpongeBob the toy (Yours, Mine and Mine)
Patrick, were you ever raised with REAL parents? Cause after this episode, I think your so called "real parents" are fake because you don't even know how to share! UGH!
4 Ignoring everything Sam does to SpongeBob and Squidward, and yelling at them for complaining (Big Sister Sam)
He clearly sees everything that Sam is doing and doesn't react and when Sponge Bob and Squidward get angry at what she does he snaps at them.
5 Destroying the Krusty Krab by throwing Mr. Krabs money in the compactor causing it to explode (Pat No Pay)
Here's a little advice to Mr. Krabs why didn't he ask for the money up front before giving Patrick all those patties.
6 Admitting to SpongeBob that he's stupidity is all an act (The Card)
He literally tells Sponge Bob that he can't expect his typical brand of stupidity he likes to mix it up keep him on his toes hinting that his stupidity for the most part is all an act.
7 Getting SpongeBob stuck even more in the wringer (Stuck in the Wringer)
8 Patrick and his parents openly mocking and laughing at SpongeBob (I'm with Stupid)
You know what they say: Stupid people are always blissfully unaware of how dumb they really are.
People like Patrick, for example.
9 Destroying everything with his karate chop (Karate Star)
