Oh yeah, and this is a booking.com commercial which has zero to do with booking rooms.

"Are you filming this?"

The guy sounds like he doesn't want his family to be filming him.  That's his choice, I guess, but don't ask me to understand it.  You are trying something really cool while on vacation- why wouldn't you want it filmed?

"Lookin' good, babe!"

We've established from the look on the guy's face that he would rather not be filmed.  His family doesn't give a damn, probably because while HIS idea of a good time while on vacation is to try cool new things and be active, THEIR idea of a good time is to sit on their asses on the beach with their electronic device hoping that dad makes a fool of himself so they can share it with the world.  Nice family, huh?

The "punchline" is supposed to be that the guy doesn't do whatever the hell he's trying to do perfectly the first time, and LOL it's so funny to see Dad Look StupidTM Let's Share.  As far as I'm concerned, the actual punchline is that a family went on vacation and only one of them even attempted to have fun and had an original experience because the others were too busy sitting around with f--ing electronics which work just as well back in the suburbs and didn't need to be brought to an exotic resort on dad's hard-earned money.  I'm rooting for another punchline- while Mom and Kids are in the hotel room watching different things on their personal electronic devices, Dad hooks up with the smoking-hot lifeguard at the hotel pool.  How's that for water sports?
