Funny Boy Versus the Bubble-Brained Barbers from the Big BangPaperback, 4 December 2012

Exiled on Earth, Funny Boy must save his new planet from an evil haircut
Never spit spitballs at your brother. That's the lesson Funny Boy learned on his last day on the planet Crouton, when his parents strapped him to a rocket and shot him to Earth as punishment for misbehaving. But just like Superman, this exiled Croutonian gained powers when he landed on the new world. He's not super strong, super fast, or super stylish, but his super sense of humor lets him crack jokes faster than a speeding bullet, and leap over boring situations with a single pun. But now he must face the least hilarious thing in the universe: the first day of school. As he tries to fit in among his human peers, Funny Boy learns that three intergalactic barbers have come to steal every strand of hair on Earth. He'll have to dust off his freshest material to stop them, because everybody knows there's nothing funny about a bad haircut.

Funny Boy Versus the Bubble-Brained Barbers from the Big Bang is the 2nd book in Funny Boy, but you may enjoy reading the series in any order.
