I like the lighter moments of this show as well as the informative aspects of learning about obesity. And hey, you never hear lines like this on "Grey's Anatomy":
"Garth, there's a big spleen there...you're making me nervous."
-- Big D watching Garth paw around the liver looking for a piece of intestines.
(Garth's response: "It's gotta be here somewhere stupid...like when you leave your keys somewhere...")
That cracked me up (the keys comment). The doctor's constant banter makes the show so much easier to watch. I also like when Big D gets on his soap box and talks about insurance.
