"Big Fudging Deal."
I have been scouring the internet for other profane statements of the obvious, and here is what I have found...
Neil Armstrong during his famous walk, actual said "This is one big Fish Taco step for mankind."
Al Michaels, at the 1980 Winter Olympics, actually said "Do you believe in Miracles - man This is a Big Flapping Deal."
Alexander Graham Bell's first words on the telephone... "Mr. Watson, Come here - I want to see you... Now Mr. Watson, this is a big frumpy deal."
And in a strange anachronism, scouring the Richard Nixon tapes - you find Haldeman telling Nixon. "This Watergate thing, it is important. it is a big Joe Biden Deal."
