Youth is Wasted on the Dick (5x15)

:

Dick tries to experience youth for the first time by partying with his students during spring break, but his drunken antics are wasted on Mary, who is trying to relive a favorite, and more relaxing, family outing instead. Meanwhile, Sally, Harry, and Tommy become enthralled with a no-nonsense state criminal investigator, who takes over Officer Don's command post when the police set up a stake-out in the Solomon's attic to spy on a suspected video pirate in the neighborhood.
