Are there any sharks The Simpsons haven't already jumped? They haven't just jumped the shark, they've gotten it pregnant, married it, and settled down to raise a family with it. (Do sharks get pregnant? Well, they are oviparous, but most sharks' eggs do develop and hatch within their bodies, so it's sort of like pregnancy. Besides, it's a metaphorical shark anyway.)
I was just going to mention something along this line, I wouldn't be a bit surprised to see the slide this into an episode some where
The baby sharks then got killed by attempting to jump other baby sharks, then got replaced by similar-looking sharks while everyone else pretended nothing ever happened.
