I am so positive that I recall an episode of Different Stokes on which Mr. and Mrs. Jefferson guest star. I bet a friend $20 and now I can't find any winning references on any website.

Please help! Is there anyone out there who can provide a link or other proof that this actually happened?

Thank You,
RB

It never happened. Gary Coleman did appear on The Jeffersons though as their nephew Raymond. This was before Diff'rent Strokes premiered - the Jeffersons episode aired in February 1978.
