Katie Couric and George Carlin were discussing the Janet Jackson Superbowl controversy.
Here's what they said as best I can remember:
Carlin: They had a commercial for a four hour erection, during the Superbowl.
Couric: They said to see your doctor if that happens. [ pause ] That's a great straight line. [ pause ]
Carlin: If you have a female doctor that would be great.
