Harry Truman actually said...

Thank you very much, Mr. Mayor.

It is the business of the President to look out for those things that are of most benefit to the most people.

I have just finished vetoing a bill which was intended to emasculate the Labor Department, and the Congress has just passed it over my veto.

I appreciate this privilege very much, and I can't tell you how much I thank you for this courtesy which you have extended to me.
