Frasier1993

Martin:
[trying to convince Frasier to lie about Niles' feelings for Daphne in his divorce proceedings] You're really not going to go down there tomorrow and blow it for him, are you?

Frasier:
Dad, there is nothing more I'd like to do than to help my brother. But I would like to find a way to do it without violating my ethics!

Martin:
But Maris is responsible for this divorce! Niles's feelings for Daphne has nothing to do with it! Now, if you cover for Niles you won't be doing anything wrong.

Frasier:
Dad, we are talking about perjury! When is that ever acceptable?

Martin:
Oh, you want an example? Fine! Let's say, uh, what if there was a comet hurtling towards the earth...

Frasier:
Oh, for God's sake!

Martin:
And you were the only person who could save the earth, but the only way to do it is by lying under oath. Would you do it then?

Frasier:
Who am I lying to, the comet?

Martin:
Oh, just answer the question!

Frasier:
All right, I suppose in certain extreme cases...

Martin:
So, then you'd lie?

Frasier:
To save mankind from a talking comet, yes!
