House, Season 5

[House is in the clinic, attempting to rise to Wilson's challenge to be civil to other people. A patient with asthma is complaining that her inhaler is ineffective.]

Anna:
I go through one a week.

House:
Are you sure you're using it right?

Anna:
Do I look like an idiot?

[slight pause while House clearly struggles not to say what he's thinking]

House:
Nope... Why don't you show me how your inhaler works.

[the patient retrieves her inhaler from her purse. She releases two puffs from it, one on each side of her neck, as though applying perfume. She looks at House triumphantly.]

[shot of House, smiling tightly, then cut to shot of the clinic lobby. The exam room door opens and the patient strides out quickly, looking angry.]

Anna:
Jerk.
