Marty : Of marriage? Newton Davis : It's not a marriage! It is a simple arrangement in which I will share my house with her and in exchange for which she will argue with me in public and generally make my life incredibly terrible. Marty : That's marriage.

Marty : What are you, insane? Why didn't you just kick him in the balls and tell him he has ugly children?

Newton Davis : So, what do you think, can you show this to Moseby? Marty : Ah... you'd better do it. Newton Davis : Why? He likes you. Marty : Davis, if I take that in there and Moseby starts carrying on about how brilliant it is... I'm going to take the credit. Newton Davis : What? Marty : Mmm hmm. Newton Davis : You're my friend, where are your ethics? Marty : My ethics are that I know this about myself, so I'm not going to take this in there and screw you over.
