one of these??? from WIKIPEDIA???
Several episodes of Father Ted featured a simpleton "Tom" sitting on a dockside wall wearing an "I shot JR" T-shirt. The gag was particularly effective as the father Ted episodes ran some 15 years after the Dallas incident. The simpleton would be used as a point of reference, eg. When you get off the Boat, look for a man wearing an "I Shot JR" T-Shirt and turn left...etc.
In an episode of The Simpsons set in 1980, Homer is seen with a t-shirt exclaiming I shot J.R..
Also on The Simpsons, Mr. Burns is shot in a parody of the Dallas finale. Campaigns ran for a time with the question 'Who shot Mr. Burns?'.
Once again on the The Simpsons, a 8th Season episode is named A Milhouse Divided.
In an episode of Friends (The One with Phoebe's Rats), an unemployed Chandler asks Who Shot J.R.? while watching TV.
In Babylon 5 an alien race called the Brakiri having received the episodes via the broadcasts arriving on their homeworld several decades after broadcast, however the conclusion of the who shot J.R. storyline was interrupted by the sun blocking the signal from earth and by the time of first contact with humans all records of the episode been destroyed or lost leaving the Brakiri in suspence over what happened, books and similar speculation on who did shoot J.R became a very profitable industry on Brakir after this.[citation needed]
The storyline was parodied on an episode of Saturday Night Live hosted by Dallas star Charlene Tilton. The episode was notable for Charlie Rocket's use of the word "smile" during the live broadcast.
Episode 5 of the USA Network series In Plain Sight is entitled "Who Shot Jay Arnstein?"
