Authorities say 31-year-old Shannon Hunter, of Lebanon, Pa., used his cell phone to call 911 on Sunday from inside a portable toilet.
Police say Hunter had been drinking and had taken off his clothes. Somehow, he immersed himself in the holding tank.
Deputy fire commissioner Chris Miller told WPMT-TV, "I've been on the job in one form or fashion for 21 years, and this is the first port-a-potty rescue I've ever had."
Police charged Hunter with public drunkenness and creating a health code violation, but they have no idea why he was in the toilet with his clothes off. They say he didn't suffer any serious injuries.
