The Brady Bunch S04E15 - Greg Gets Grounded

Bobby tells his parents that Greg nearly got into a freeway accident because he was reading the cover of a new record. Mike and Carol suspend Greg's car privileges for a week, but Greg has plans to take out his girlfriend Rachel. When Greg decides that his father's directive has a "loophole" and takes a buddy's car to procure rock concert tickets for the date, Mike really hits the roof and grounds him. Greg talks his way out of the severe punishment but is bound by "exact words" ... and it leads to a drive-in movie date that neither Greg nor Rachel will ever forget.
