Why can't folks just behave like these guys ... who are going on a nice, recreational dive together? The only laughter you'll hear outta these fellows is after the dive, when they're telling their buddies how much fun they had diving together ...

I certainly don't like to criticise divers I don't know, but I am pretty sure the dude in the middle with the rebreather has his mask on the wrong way around.
