How did I miss this? Recently came up in a YT channel.

Is there more? I've seen this gameshow around, but never this messy stunt before.

You didn't exactly "miss it." This has been around for years and only resurfaced on a WAM-centric channel in the last week. But the clips themselves date back to (checks HD full of clips)..... May 30, 2014!

And I guess you already figured out by now, but BLT loved this game so much they did it.... never ever again!
Which is why we celebrate "BLT Did Something Right For Once Day" every May 30th. (Maybe just me.)

Anyway, here's the full game still up on YT. There's another (lesser) female pairing, along with guys if you're into that.

Jez... only 1 gameshow episode with this much mess?
