To celebrate the 50th anniversary of Warner Bros. Television, TV Land will air a marathon of Warner Bros. shows on the weekend of June 11-12.
Two episodes of 
Falcon Crest, which starred 
David Selby as Richard Channing, are included in the marathon.
"Ashes to Ashes," which originally aired in May 1984, will be shown at 12:00 am on Sunday, June 12. This was the cliffhanger episode of the third season. It involves a plane crash.
"Requiem," which originally aired in September 1984 as the first episode of the fourth season, will be shown at 2:00 am on Monday, June 13.
For the 
Kate Jackson fans, the first episode of 
Scarecrow and Mrs. King will air at 3:00 pm on Saturday, June 11. It will be repeated at 1:00 am on Sunday, June 12.
Dennis Patrick appears in the 
Dallas episode airing at midnight on Sunday, June 12. "A House Divided" is the episode in which J.R. gets shot.
I've probably missed some other DS connections. The complete schedule can be found
