Sidney's Comet by Brian Herbert

Bestselling author Brian Herbert’s hilarious first novel. For centuries the slops that inhabit the Earth have been rocketing their refuse into the Galaxy, carelessly littering the cosmos with wrappers and peelings and bottles and cans. But now the universe is about to get even. An immense comet of garbage has been sighted on a collision course for Earth! Only one man can stop it: a human discard, a lowly government worker who dreams of becoming a Space Patrol Captain but could never pass the physical—the unheroic, the imperfect, the one-and-only Sidney Malloy!
