Joel Fish, 20, of Queensbury, was arrested after he was discovered at the O'Leary Funeral Home in Canton, 200 kilometres north of Syracuse.
Debra White, wife of the home's funeral director Joe White, said she noticed a broken window and open door to the casket display room when she awoke at 6:30 a.m. Thursday.
Inside, she saw a boot and pair of pants on the floor and a pair of knees sticking out of a stainless steel coffin.
Fish, who police said was intoxicated, was treated at Canton-Potsdam hospital for cuts. He was arraigned and released to return to court at a later date.
The funeral home estimates the damage from the burglary, mostly to the coffin, at $4,000 US
