House, Season 2

[House is searching frantically through Melinda's hair for a tick]

Dr. Cuddy:
Except that ticks aren't usually invisible.

Dr. House:
They are until you FIND THEM! [holds up comb triumphantly] No, that's dandruff. Okay, well, that wasn't nearly as dramatic as I'd hoped. It just means that next time'll be even better!

[...]

[Cuddy, Wilson, and Melinda's parents burst through the elevator doors, only to see House searching for a tick with his head between her legs.]

Lewis:
You sick, miserable...! [He rushes into the elevator]

Dr. Cuddy:
What are you doing?

Barbara:
Oh my god!

Dr. Wilson:
Wait!

[The father has House pinned to the back of the elevator. House hold up his hand to reveal the elusive tick]

Dr. House:
See? Told you it'd be more dramatic.
