Frasier and Martin in “To Tell the Truth”

Frasier

I can't believe you're being so casual about this. You realise your asking me to do something entirely unethical?

Martin

Oh for God's sake. Nobody's even going to know!

Frasier

That's the point! Ethics are what we do when no-one else is looking. For heaven's sake I learned that from you. Are you saying you wouldn't have any trouble with this?

Martin

Let me tell you something. One time when I was on the force I saw a guy shoot somebody. When we caught him I started to read him his rights. But he slipped out of his cuffs and he swung at me so I didn't have a chance to finish. Two months later, I'm on the stand and his lawyer asks me if I read him his rights in full. Now, if I say no, this guy walks. And this guy's been in and out of jail all his life; he could have read me his rights. So I say "Yes, I did, I read them in full." I lied under oath. Now you might think I did an unethical thing but there's not a doubt in my mind that I did the right thing.
