Kid Flash, by Anthony Brown

Many youth like sugar and are partial to dares. So one day, an already-hyper Josh took a bet challenging him to drink a pound of sugar dissolved in water. He drank it and, two minutes later, he became like Kid Flash out running cars and lapped the planet in 0.2 seconds.  From then on, he was Kid Flash, conditionally, when he ate only sugar or sweeteners.  Some time later, on Halloween, he ate all his candy and went out for more. Half way back to the house, he ran into his friends. Just then his head exploded all over his friend Fin!  The lesson learned here is too much sugar is a bad thing, and dares are killer!
