Coast Guard Air Station New Orleans

The man who fell off a Carnival ocean liner and treaded water for 20 hours before being rescued, but there's one big mystery -- how many drinks did he consume before going overboard?

The harrowing experience last week in the Gulf of Mexico was described on Friday's 'GMA.'

He admits that he had been drinking on the day of the fall. He won an air guitar contest.

The last person to see the 28-year-old was a family member. He does not remember falling off the ship or hitting the water.

He remembers that he was in the ocean without a boat. He was taken to the hospital after the fall. It's unbelievable!

At least one shark was seen as James was treading water in a feeding ground. You have to watch the video and listen to how he survived.

He swam towards the vessel after seeing a freighter. The first thing he did when he got out of the water was warn a military man that he was naked.

The funniest person of the year is this guy.
