Kenny died so many times on South Park that Trey Parker Matt Stone started to let him live. He’s been struck by lightning, attacked by mutant turkeys, drowned by Satan’s goldfish and even died of boredom.
Evantually the writing team got so sick of the gag that they stopped it all together. Now Kenny’s usually a sexy princess. Yummy.
I think a lot of people probably haven’t noticed. I couldn’t care less. I am so sick of that character.
– Matt Stone in a 2002 interview
Kenny hasn’t died since season 16 now, but I’m sure there will be one on the way soon. Maybe death by series cancellation.
