How can one complicate the making of a deal :)

Sir Humphrey: "Prime Minister, I have had another word with her. To put it simply, Prime Minister, certain informal discussions took place involving a full and frank exchange of views, after which there arose a series of proposals which on examination proved to indicate certain promising lines of enquiry, which when pursuit led to the realization that the alternative courses of action might in fact, in certain circumstances, be susceptible of discreet modification, leading to a reappraisal of the original areas of difference and pointing a way to encouraging possibilities of compromise and cooperation which if bilaterally implemented with appropriate give and take on both sides might, if the climate were right, have a reasonable possibility at the end of the day of leading rightly or wrongly to a mutually satisfactory resolution."

Jim Hacker: "What the hell are you talking about?!"

Sir Humphrey: "We did a deal."
