What's My Line
I'm an avid fan of What's My Line and the one with Debbie Reynolds (the first one as she was invited several times) is one of my favorite, I never get tired of it.
I'm pretty sure most of the fans have already seen it but maybe some never did and it also shows how genuinely sweet and funny she was (RIP)
