Esther Williams whispers something to Jack on What’s My Line, broadcast on 12 January 1958.
I AM LOLING. <3
I was afraid I would wake my parents up. xD;
BUT OMFG I WAS SO BUSY BEING AMUSED BY JACK THAT I DIDN’T EVEN REALIZE SHATNER WAS THERE. WHAT EVEN.
Some people have said it sounds like he’s impersonating Peter Falk as Columbo seeing as he was filming The Great Race with him when this was aired. Dunno if it’s true or not but it certainly does sound like it!
