Oh, I thought you were joking!?
Of course you know who Kate & Milt & Burris are, so you must mean K-Ci and Jojo... I didn't know who they were either, but apparently they were a male signing duo doing romantic r&b in the late 90's / early 00's. You can google/youtube them. (Totally not my style!)
But Milt & Hank knew who they were and were cracking up big time on the panel as they were cutting to commercial. When I checked out who they were, I got the joke too. I have to hand it to Kate, that was some pretty funny stuff and I bet she really impressed the boys with that one, even if 90% of Canada had no clue what she was talking about (including me). I love wacky, irreverent and asinine humor like that.
Still no takers on which game it was?? Argh... I'm going to have to *carefully* watch each game's panel time now then. I'm starting to wonder if it's 2018, not 2019... but I could have sworn it was 2019.
I thought it was a joke / razz too lol
The explanation was worth the wait
