He's either crazy or he's Forrest Gump.
Nah, he's got brain damage. Oxygen deprivation.
He was on a long submerged cruise with a defective O2 sensor.
It's the only explanation that makes sense.
To serve as quartermaster on a nuclear submarine, he had to at one time have been normal.
Now he's as loony as nadin.
It wouldn't surprise me if everyone who was on that boat has gone as crazy as Abbott.
