The 40-year-old man, whose name was not reported, dropped his wallet into the sewer in an underground parking garage and tried retrieve it, thelocal.fr reported Monday.
When grabbing for his wallet, he slipped and ended up somehow getting his head stuck in the sewer. The man stayed in that position overnight until someone using the parking garage spotted his feet sticking out of the sewer the next morning.
The passer-by called emergency services, who pulled the man out and resuscitated him. He was suffering from hypothermia and was taken to a hospital for treatment.
After rescuing the man, police noticed he had been siphoning off waste oil from his car into the sewer at the time he got stuck, which is an offense in France.
The man was ticketed. Punishment for the offense can carry up to two years in jail and a $97,000 fine.
