Gordie Howe on What's My Line? (Taped Sept. 6, 1973)
 

Soupy Sales got it because after Gordie was asked if he played in Detroit (no) - Soupy asked 'Do you play in Houston?'

This guy beat up people? Typical hockey player, seemed so embarassed when his accomplishments were being listed. This is pretty interesting though, I dunno how famous hockey or especially WHA hockey was in the US at the time but the panel seems to have a decent idea. Maybe it's worst now where I dunno if the avg American middle-aged adult would even know Sidney Crosby.

Btw was that the whole premise of the show? What a boring show though we're in no position to judge with terrible modern reality TV.

that was fun.
