Metabolizing carbohydrates just for me

Who else but Weird Al would write a song about his pancreas? My favorite part, because the physics reference was so unexpected, is

My pancreas attracts every other
Pancreas in the universe
With a force proportional
To the product of their masses
And inversely proportional
To the distance between them

But you have to love the bits about lipase, amylase, and tripsin, too.

On the same album (Straight Outta Lynwood), his "White and Nerdy" is absolutely brilliant, although a little too close to home!
