The Venture Bros., Season 3

[The Order of the Triad put on a safety sketch...]

Jefferson Twilight:
Killin' Blackulas with a sword is cool. But you know what's really cool? Safety!

Dr. Orpheus:
The Order of the Triad have many strange and mysterious enemies!

The Alchemist:
Enemies...of safety!

Jefferson Twilight:
One of our enemies is invisible!

Dr. Orpheus:
And he can enter any home through the ground! He's waiting for you right now in the basement!

The Alchemist:
His name is Radon! And he will give you lung cancer!

Jefferson Twilight:
Lung cancer? But, Al, I don't smoke!

Dr. Orpheus:
Of course you don't, Jefferson! Because smoking is more evil than the hoary denizens of the Underworld! And if you did smoke, we'd know it. Because we have a SMOKE DETECTOR in every room!

The Alchemist:
With fresh batteries! Remember: if your smoke detector doesn't work, the silence...

All:
Could be deadly!

[They bow. As they look up, they notice that all of the children have gone.]

Jefferson Twilight:
When did we lose 'em?

Dr. Orpheus:
That was my fault. I really hit them with that "radon" part.

The Alchemist:
We never get to my song!
