The "Patrick Lecturing SpongeBob" scene is a super-infamous scene from the HYPER-infamous episode, The Card. In this scene, Patrick says this: "SpongeBob, you can't always expect my usual brand of stupidity. I like to mix it up. Keeps you on your toes.
Why It's Not The Usual Brand Of Stupidity[]
If the episode itself isn't bad enough, Patrick reveals that it's on purpose. It's ALWAYS on purpose. Some excuse, Patrick. Even if there isn’t any continuity whatsoever, and it’s just a quote for this episode only, it still makes Patrick a horrible monster for admitting that he’s being an idiot for the hell of it.
Also, it completely misses the point of Patrick's reckless behavior, the whole point of him being reckless is that he's oblivious to what he's doing, and this scene completely retcons all of that by saying that he knows that he's doing something bad.
