Oh cripes...I had to go look: according to wikipedia: Don Draper, **** Whitman's birth year is estimated to be late 1925 - early 1926...in his early 20's he runs away and enlists in the Army and is almost immediately sent to Korea, etc., etc., so we're talking late early 50's...he marries Betty in 1953...although Wizard of Oz originally released in 1939, it exploded into popularity in 1956 with the TV release, and featured a revolutionary ending with Dorothy waking from a dream where the real life people around her resembled characters from the dream she awoke from...
...I have too much time on my hands today, obviously...
