Snooki and JWoww definitely don't take themselves too seriously ... or at least that's what they're trying to tell America!

On YouTube, the two Jersey Shore castmates enjoy mocking themselves as their alter egos Flow & Nancy.

In between cracking themselves up, Nicole Polizzi and Jenni Farley lay on their thickest Jersey accent while telling America all the things that are wrong with Jersey Shore ... and why the "disgusting" show needs to be taken off the air.

After watching their attempt at being funny, they may want to stick to fist-pumping.
