The caped crusader was sitting behind the crew rest area on the flight, which on this particular aircraft is a block of 6 economy seats curtained off. His seat, and the one next to it are some of the most desired in economy, tons of legroom, quiet in front of you, really an area where you should nicely be able to get a nights sleep .
This man decided to help himself to the land of Nod by taking Ambien and washing it down with a cocktail or two. ( Crew members everywhere know this is not going to end well...)
Sometime mid flight he decided he needed to relieve himself. He tried to enter the crew rest area, thinking in his drug and drink haze it was a toilet. Mercifully for everyone, he did not urinate there. If he had, this blog post would have been written from prison as I surely would have killed him.
He somehow peed in his pants at that point, THEN stumbled back to the bathroom. This was the time he decided naked was better than clothed, and took off all his clothes and put them in the trash can. He walked back to his seat in the state he was born in.
A crew member who discovered his naturalist state gave him a blanket to cover himself up in. He decided than that the most logical way to wear it was as a cape. I would have opted for a sarong, covering his man bits would have been a better choice, but who am I to judge...
