You have to have grown up with it and gained an unconditional love of the characters. You don’t care that they are an asshole to a character you don’t like.
Look at Kramer he is so stupid he can’t figure out a washing machine! Lol he’s going to try to pour a bunch of detergent in next and act like he’s drunk because he’s that stupid! He’s so funny!
Edit: Remembered it wrong. He was pouring concrete into the washing machine. Classic asshole
