Saw some threads about game shows and it made me remember something. Around 2002ish, there was a bet involving girls and a dunk tank of gunge. My mind is very hazy (horrible memory ). I have searched high and low all over YouTube and a bunch of Russian sites for it to no avail. If anyone has it, I will be eternally grateful. There's a lot of stuff from this show online but the majority seems to be lost to time.

Since it was so long ago, you're likely out of luck, but you can try asking this guy: https://ibetyouwillfemales.tumblr.com/
who is an expert of sorts when it comes to IBYW.
