20-year-old Christopher Shirley was reportedly so under the influence of alcohol and marijuana that he conked out while getting his mug shot taken.

Cops in Porter, Montgomery County,Texas, say Shirley fell asleep behind the wheel after backing his trunk into a parked car at the local Walmart. He was so seriously wasted, a passersby was unable to wake him. And because he'd dozed off with the engine still running, the Good Samaritan called the cops, who managed to rouse him long enough to determine he was highly intoxicated

Shirley was charged with DWI and taken to the county jail, where he appeared to knock out again while getting his booking photo taken.
