So yeah those are a couple of satisfying moments in the show that come to mind, what's your opinion?

Cartman's look on his face when he realised he killed his own father

Kyle attacking Cartman at the end of Kenny Dies was pretty satisfying

None of these are satisfying except the Butters one

Shelly and Cartman getting back at Skyler. Too bad it was kind of ruined when they tried to redeem Skyler at the end of "Timmy 2000".

Wendy beating up cartman was a moment that i can rewatch it again @Sam Katawazi
