And now that I think about it, and the Mike Farrell Diffrent Strokes connection has been established
Farrell recently gave an interview to Michelle Phillips, who, of course, was the step mother of MacKenzie Phillips, who was on One Day at a Time with Pat Harrington (Dwayne Schneider) who, during the Korean War, was in the army (just like B.J. Hunnicutt).
This newly realized Army Connection opens endless possibilities!
BTW- Nancy McKeon (Jo Polniaczek on The Facts of Life) had a private audience with The Pope, just like Father Mulcahey on M*A*S*H, so theres another Army Connection.
Mindy Cohen from the Facts of Life also did the voice of Velma Dinkley on Scooby Doo and in the original one, Don Messick did the voice of Scooby and was friends with George OHannlon who did the voice of George Jetson and Elroy Jetson was played by Daws Butler (who also voiced Quick Draw McGraw) and he worked with Nancy Cartwright (Lisa Simpson) and her father, Homer, was in the Army in one episode.
