One of the all-time great sitcom episodes. But it's also a real shame that the series can no longer be aired or released to DVD due to the totally messed up licenses schemes involved:http://www.wired.com/entertainment/music/news/2005/03/66696?currentPage=all
From the above article:
"As the DJ spins the record as he's talking to Loni Anderson, if there is music playing even for a couple of seconds, then the people producing the DVDs would have to license it."
Insane and a loss to TV history...
