"F Minus is a strip short on life lessons, precious moments, and pearls of wisdom. It tackles life's serious issues, pins them to the ground, and steals their lunch money. Then it feels a little bit guilty and gives some of it back. 'I draw my material from my experiences at a wide array of failed careers,' says Carrillo. 'Over time, I have worked as a pizza cook, Web site designer, dancing costumed character, portrait artist, insurance drone, waiter, custom framer, camel ride attendant at the zoo, and the guy at the airport that waves orange wands at the airplanes. As varied as these jobs were, eventually I had the profound realization that they all had two important things in common: each offered a wealth of comedic inspiration and there was always a creepy guy named Larry.' Life isn't fair. But it sure is funny in F Minus."--Amazon.com.
