Sorry, but Jacko, Farrah and Ed McMahon never appeared together on "The Tonight Show"

Boy, here is a great lesson of "if it seems too good to be true ... look it up!" Fellow Twitter nut Troy Diggs at KMBC-9 passed along this tweet this evening as we were all remembering the late King of Pop:

@ryanmer On 09/18/1979, Farrah Fawcett & Michael Jackson were both guests on the Tonight Show w/Johnny Carson, co-hosted by Ed McMahon.

Great factoid, and I posted it immediately, and it rapidly spread from there. A few minutes later, it occurred to me that mebbe I should've checked it out first. So I went to JohnnyCarson.com, the official "Tonight Show" site maintained by Carson Enterprises, and went to its comprehensive, 30-year guest search function. See the video for yourself:

Not only did Jacko never appear with Farrah Fawcett, he never appeared on the "Tonight Show" after the Jackson 5 days, according to the guest database.

And in fact, a search for 09/18/1979 revealed ... Johnny didn't do a show that night.

Oddly enough, the late Fawcett appeared twice on the "Tonight Show" with the Temptations.
