I grew up loving Bugs Bunny (still do for that matter) but it was Groucho's absolute and total irreverence for and hostility to authority in any form that "warped" me for life. The best thing I ever read about Groucho was that "he would insult a king to make a beggar laugh."
And as for "I can't think of anything to say -- maybe you can suggest something -- in fact, you do suggest something -- to me, you suggest a baboon." 
And then there is this exchange with the great Margaret Dumont:
Rufus T. Firefly: Not that I care, but where is your husband?
Mrs. Teasdale: Why, he's dead.
Rufus T. Firefly: I bet he's just using that as an excuse.
Mrs. Teasdale: I was with him to the very end.
Rufus T. Firefly: No wonder he passed away.
Mrs. Teasdale: I held him in my arms and kissed him.
Rufus T. Firefly: Oh, I see, then it was murder. Will you marry me? Did he leave you any money? Answer the second question first.
Groucho was one of a kind.
