I just talked to my son and he says the only thing he can think of would be that - even though he thought it was funny himself - he said that the navy would not like that video because it shows navy guys goofing off, on a ship, and not doing their job...and the tax payers were paying for them...he said it would be considered tastless. Again, he said he has no idea for sure - but that is his take on it...
Goofing off? Tasteless? Oh please! I'd be worried if the guys on a sub WEREN'T goofing off sometime! It's good for morale and their mental health!
