Tonight's Mad Men included a scene in which a character sang and danced the 1920s standard, "The Best Things in Life Are Free." Normally this would count as a spoiler, except that even with that knowledge, you'll never see it coming. Here's a look at Mad Men's greatest musical moments.
But first, here's a look at actor Robert Morse — who plays the now deceased Bert Cooper — in one of his most famous roles, that of J. Pierrepont Finch in the 1967 film version of How to Succeed in Business Without Really Trying. Morse won the 1962 Tony Award for Best Actor for his Broadway incarnation of the character.
