Cheaper to leave the lights on?

The bane of the Straight Dope is those little factoids someone told us years ago that we never questioned, or even heard elsewhere one way or another, so let me get to the point.

A buddy of mine from decades ago once claimed that turning a light on and off during the course of uses more electricity/costs more money than just leaving the light on during waking hours. (Mind you, this was back in the 70s, before these freakishly long-lasting light bulbs he have now were invented.)

Is it even remotely possible that this is true? My dad was of the "Turn the lights off when you're not using them" stripe and that's always been my inclination.
