It's Think Thursday here at the mentalfloss.com Brain Game. Put on your sitcom thinking caps - or take a stab if you're not a fan - and see how well you do with today's challenge:
Which four major characters on TV's M*A*S*H
received promotions during the show's run?
1. Frank Burns was promoted from Major to Lieutenant Colonel (upon his exit from the show).
2. Father Francis Mulcahy was promoted from First Lieutenant to Captain.
3. Max Klinger was promoted from Corporal to Sergeant.
4. And a BONUS if you remembered that Walter "Radar" O'Reilly temporarily held the official rank of Second Lieutenant (after Hawkeye and B.J. won the perk for him in a poker game).
