Holy shit, I just remembered this Canadian game show that I loved when I was a kid. I'm pretty sure it was like a version of the Newlywed game (where contestants guess the answers of their partner) but with siblings instead of couples and kids instead of adults. And uhhhh it was fantastic. I always dreamt of being on it with one of my brothers. God, it was such a good show. And there are episodes on YouTube! Ahhhh!

Why the hell did they never show reruns of this show on The Game Show Network? I was constantly waiting for that day to come.
