As the current season of Mad Men was being filmed, January Jones (who plays Betty) was having a baby. Instead of ignoring the pregnancy or writing it into the plot, the writers put Ms. Jones into a fat suit and had Betty's weight gain become a rather dramatic plot element.
In the meantime some guys at SOUTH Music & Sound Design decided to commemorate the development with a song:
Yes, it is rather mean. But I choose to see it as a send-up on the show's dramatic excesses rather than a put-down of overweight people in the real world.
What do you think?
At least they didn't make fun of her placentophagy...
