You know, the one with the full theme song that REPEATS the "If you threw a party" lines twice, and has some extra scenes? I hear it never appears on the DVDs?

It was only used in syndication, not during the original NBC run. Off the top of my head, Bringing Up Baby is the only one I can think of Lifetime had the long version. During the 1990s syndication, it was used more often on various episodes.

Here are the episodes that Lifetime used the super long intro:

"Stan's Return"
"Joust Between Friends"
"The Stan Who Came to Dinner"
"Forgive Me Father"
"Bringing Up Baby"
"Nothing to Fear but Fear Itself"
"A Visit from Little Sven"
"We're Outta Here" (Part one)
"Blanche Delivers"
"If at Last You Do Succeed"
"Love For Sale"
"Never Yell Fire in a Crowded Retirement Home" (Part 1)

Why was an extended opening created for syndication episodes but yet they were chopping the episodes by cutting out scenes??!! It makes no sense.
