I assume I'm late to this party (I'd never heard of this show until a few days ago). Innuendo Bingo is a BBC Radio 1 show where celebrities listen to radio and TV clips that contain lines that can be misconstrued as sexual. They have glassfuls of water in their mouths that get spewed onto each other as they bust out laughing at the innuendo.
I've had some real bust-out moments of my own (sans water or someone to gob on) watching these. I especially love it when they get so overly giddy that they spray their "opponent" even before they arrive at the innuendo.
