Gravity Falls, Season 1

[Wendy throws a water balloon in Stan's face from atop the high lifeguard chair]

Wendy:
Hey, Mr. Pines.

Stan:
Wendy?! Where's the lifeguard?

Wendy:
I am the lifeguard. I make the rules, sucka! Boosh! [throws more balloons]

Stan:
[fleeing] AAH! SHE'S ATTACKING ME WITH WATER!

[Wendy, Dipper and Soos laugh]

Dipper:
Wow, you work here?

Wendy:
I found out lifeguards get free snack privileges. Plus I get the best seat in the house.

Dipper:
Yeah, you do! [laughs rather exuberantly for a moment, then whispers to himself] I've been laughing for too long.

Soos:
Dude, are you and Wendy having a secret staring contest? 'Cause I think you're winning.

Dipper:
Soos, shhh!!
