Nasty Stan. Chronicles of the Madmen, #1

Book One of the Chronicles of the Madmen. Stan Evans is the embodiment of filth and laziness. Life has been squeezing him for a long time, but the final blow comes from his ex-girlfriend, who demands child support. Desperate to avoid court, Stan decides to rob a late-night convenience store. Naturally, everything goes wrong - the police catch him red-handed at the scene. After a short, pathetic escape, he finds himself trapped in a dark alley with no way out.
or so it seems. In a blink, Stan and the pursuing police officer vanish - abducted by extraterrestrial forces. When they wake up aboard a strange spacecraft, they realize they're trapped, though not in a strictly lethal way. And soon the representatives of an alien civilization will deeply regret one thing: of all the humans they could have taken aboard, they chose Stan. His personality, foul habits, and utterly disgusting manners will make sure of that.
