Flight of the Conchords, Series 1

Murray:
[To Jemaine] I've told you. When you are in a band, you don't get with your bandmate's girlfriend. Past or present.

Jemaine:
Yes, well, thanks for that.

Murray:
You get a love triangle, you know, a Fleetwood Mac situation. Although there was four of them, so more of a love square. But you know, no-one gets on.

Jemaine:
Ok, I see.

Murray:
Mind you, they did make some of their best music back then.

Bret:
Rumours.

Murray:
No. No, it's all true.
