"Jenny Jones" fans watching Channel 20 yesterday afternoon got a look at Alan Abel, a major TV hoaxer, as he claimed his wife had used Superglue to attach his penis to his leg after she caught him fooling around ...

The episode had been taped two weeks ago in Chicago, and skeptical researchers for Telepictures, which produces the syndicated program, had already put the episode, titled "Getting Revenge on an Unfaithful Loved One," on hold, pending verification of the medical facts ...

But the program had meanwhile been satellited to Warner Bros. Domestic Television in Los Angeles, distributor of "Jenny Jones." Yesterday morning out in Los Angeles, someone accidentally put the wrong show back up on the satellite for client stations ...

Warner Bros. estimated about 80 stations, including three in the top 10 markets, carried the hoax ...

The hoaxer posed as a man named Bruce Spencer to get on the show. Warner Bros. said he had pulled similar stunts on "Donahue" and "Sally Jessy Raphael." His story led off the disputed episode yesterday ...

Minutes into the transmission, Warner Bros. realized it was the questionable episode and stations were notified by fax not to use it and a substitute show was supplied. Some 60 stations caught it, according to Warner Bros. ...

Channel 20 here was not one of them. "We received the fax about 35 minutes into the broadcast and by then he was long gone," said Sandy Pastoor, programming boss at the Paramount-owned station. "So we just continued with the episode." The station received no phone calls about the episode ...

"We have a very good verification process," Warner Bros. senior vice president Barbara Brogliatti said yesterday. "The episode was on hold pending medical verification. It was just sent out accidentally" ...

"Syndicated shows have been a target of this kind of thing in recent months," according to Brogliatti, "and have had to really clamp down on the entire process. It's now extremely difficult to pull this off; it's much harder to get through Step 1. This time it worked -- and then it didn't work" ...

NBC Vote of Confidence

A disclaimer, which an NBC spokeswoman described as "probably the largest and most elaborate in network history," appeared again Sunday night before the repeat telecast of "Ancient Prophecies" ...

The program, which made a fairly strong showing against the Grammys on CBS when it first aired in March, focused on ancient and modern-day "prophecies relating to the year 2000" ...

The network's department of program standards "wanted to avoid a 'War of the Worlds' panic," the spokeswoman said. "We were afraid that viewers might take the show to heart and wanted to provide as much of a context as possible," producing the following disclaimer:

"The following is not a news program or a documentary.

"The people appearing on camera are not necessarily experts and are expressing personal opinions only.

"Although significant opposing viewpoints exist, they are not included.

"The information presented represents unsubstantiated anecdotal accounts of events, interpretations of writings, and speculation about the significance of certain predictions.

"Some predictions by the same sources, though not mentioned, have been proven inaccurate.

"Events are dramatized, simulated and re-created."

And finally: "It is not the intention of the broadcasters to suggest that any prophecies are true, and all conclusions about the future, drawn by persons in this program, are purely conjecture" ...
