What they would do.

John: *screams and blows the whistle at everyone even if they weren't doing anything wrong.*

Paul: *puts really tinted sunglasses on so no one can tell if he's sleeping or not.*

George: *eats an ice cream cone from the stand and twirls the whistle around his finger.*

Ringo: *sits on the guard stand wearing a huge hat to keep the sun off him and has sunscreen lathered all the way up his legs and all over his nose.*

What they would say.

John: Hey, no horseplay! *blows the whistle so hard spit flys out of it* No running, you idiot! Do you want to break your neck?!? Jeee-sus. Hey, hey, kid, stop dunking your sister! That's no way to treat a lady. What do I care if she started it? *blows the whistle again at a kid on the diving board.* Don't dive, there's a wiseacre hanging out under the board. God, it's like running a nursery around here.

Paul: *snores loudly when a kid tugs on his sleeve* C'mon, let me sleep. *sits up straighter and takes off his sunglasses* What?!? Did you just say there's a fat kid drowning? *looks to the deep end and then looks at the cold water.* I think I'll pass on that . . .

George: What do you mean you want my ice cream cone? Go get your own. *starts twirling the whistle around his finger faster until he loses his grasp on it and it goes flying into the pool* Someone get that for me. I would do it myself, but I'm eating.

Ringo: *pushes his hat up out of his eyes* Please stop running, kid. Could you stop running? The concrete's slick, you know. Stop running. Stop running. Stop running! Agh! Someone call the ambulance, we've got another broken leg.
