Surviving the World
A Photocomic Education by Dante Shepherd
Lesson #693 - Muffins
I think I'll just quote from Wikipedia on this one, whether it's right or wrong:
"Healthy muffin recipes using whole grains and such natural things as yogurt and various vegetables evolved rapidly. But for healthy muffins to have any shelf-life without artificial preservatives, the sugar and fat content needed to be increased, to the point where the muffins are almost indistinguishable from cupcakes."
In other words, muffins are diabolically clever beings that will find ways to survive and kill you no matter what.
