What they would do.

John: *would do insane stunts and end up wiping out ten times*

Paul: *would spend more time sunbathing than actually surfing*

George: *would put his board in the calm shallows and meditate on it until a massive wave comes through and washes him on shore*

Ringo: *would get on a little wave and start screaming and lose balance*

What they would say.

John: Hey, Paul! Check this out! *does a backflip and then misses his board in the way down* Don't watch that. This one will be better. *does a Lennon dance on his board while he's riding a huge wave and then falls off, getting swallowed by the wave* Tell me you didn't see that!

Paul: *eyes closed, napping on his board on the beach* Oh, yes, John. That was a magnificent trick. Bravo. *claps hands and then drifts off while John is still talking to him*

George: *meditating* Peach in, green out. Ommmmmmmmmmm. *cracks an eye open* Do I hear a giant ~ *gets kicked off his board by an aggressive wave and winds up on shore, missing one of his flip flops and his hair a mess*

Ringo: Oh, my God, this is the biggest wave in history! *riding a two foot wave* Keep calm, Richard. Keep calm. You're doing great. *sees a fish swimming nearby* IT'S A SHARK! *loses balance and falls in*
