its an abdominal exercise created and done by Ben Cranston. Done by standing someone on your chest and then doing a situp so they crunch against you.
Ben: Boy, this Cranston Crunch is a real ab killer!

Opal: What's a Cranston Crunch? I've never tried that.

Ben: You're gonna love it. Stand on my belly, I'll show you what it is.

Patty: Easy, dad, she might fall off.

Ben: (Laughing) Who cares?! Its a real gut buster.
