King of the Hill, Season 10

Hank:
I still can't believe Bobby cheated on his paper route. I don't even know know how to punish that.

Peggy:
Well, the pressures of journalism can be very intense, even I have felt it. But today, I really knocked one out of the park.

Hank:

Peggy:

Hank:
Ammonia and bleach? You told people to mix ammonia and bleach?

Peggy:
Only if they want bathroom fixtures that shine like the sun.

Hank:
Peggy, that's the recipe for mustard gas. Arlen will be covered with a cloud of poison

Peggy:
BWAH!
