Peep Show, Series 1

Mark:
What does your sister do?

Toni:
Not much. She's got leukaemia.

Mark:
(That's what you get for trying to flirt.)

Mark:
That's terrible. I'm so sorry. I suppose... I mean, at least it's not cancer.'

Toni:
It's a form of cancer.

Mark:
Man. That's terrible. My gran... died of cancer. Although, hopefully, your sister... won't. Obviously. Listen, let's talk about something else. Something fun.'
