When a man attempted to siphon gasoline from a motorhome parked on a Seattle Street, he got much more than he bargained for.

Police arrived at the scene to find an ill man curled up next to a motor home near spilled sewage.

A police spokesman said that the man admitted to trying to steal gasoline and plugged his siphon hose into the motor home's sewage tank by mistake.

The owner of the vehicle declined to press charges saying that it was the best laugh he'd ever had.
