In the same ballpark as Dons window line is one Roger delivers over the phone to Betty: I know you have to be on the same page as him Again it seems rather innocuous, but then consider that Roger is delivering the line in 1963, and the phrase doesnt actually seem to have been first used until the mid-70s. Obviously the writers werent all on the same page when it came to fact-checking that one. Other phrases that have been called into question include Peggys use of Im in a very good place right now and Sal Romanos awwa!
