My roommate has that new show "Medium" on, and I hear laughter. Turns out Patricia Arquette's character is watching a B&W "Password," and the password is "ABSURD." And for some reason, the audience found the clue for absurd hilarious. I of course noticed Allen, and one of the celebrity partners was Betty White. Not surprisingly, there was no GSN logo, but I'm guessing the viewers are led to believe she was watching a generic game show channel.

Anyways, for any of the diehard B&W Overnight viewers, anyone might know when this ep. aired based on the very vague info I gave?

That sounds familiar. I don't know if it's from having WATCHED the program, or
RECORDED it.

Of course, you know Betty's made more than ONE apearance on Allen's B&W Passowrd, right? IF the OTHER celebrity was Arlene Francis, then it is the one I have. That would be: Ep# 169 OB Date: 05/20/65.

Hope this helps!
