Phineas and Ferb, Season 4

Liam:
[pinning down Perry with his boot] AHA! GOTCHA! [puts on Perry's fedora] My greatest hunt ever ENDS RIGHT HERE!

Doofenshmirtz:
Stop what you're doing, McCracken! STEP AWAY FROM THE PLATYPUS!

Liam:
Doofenshmirtz!

Doofenshmirtz:
I like you to meet my ladies. [two old groundkeepers arrive at his side] Ruth and Esther!

Liam:
[scoffs] Docents. [Ruth angrily points to a "Keep Off the Grass' sign which Liam is standing next to] Aw, not again! [throwing the fedora back to Perry] I'll be right be back! I know how to hand these ladies. [to the ladies] Uh... the sign must've been installed... I've never seen it before.

Ruth:
Nice try, Liam, but this is you third infraction as of many weeks! Hand over your membership card!

Liam:
What?! Let's not get crazy now! [turns in his card]

Ruth:
All of your gardening privileges have been revoked for ten days! Esther will escort you off the grounds!

[Esther bring in a wheelchair for Liam to sit in]

Liam:
But I can't leave. It's my natural habitat!

Ruth:
Your file says you're from Pittsburgh!

Liam:
[speaking in an American accent] But it's not my fault! It's HIM! [points to Perry] It's the platypus you want!

[Ruth and Esther spot Perry, and Liam's wheelchair starts to roll down the hill, taking a screaming Liam with it]

Ruth:
Aw, how cute he is. What a handsome platypus.
