You're at a small dinner party with a new SO, showing him/her off to your friends for the first time. After dinner the host wants to play the 'I've never...' drinking game. Everybody has their drink. As a joke, the host says "I've never...buried a dead hooker in the desert". Your SO is the only one who takes a drink. Awkward laughter ensues. The next person says "well, um...I've never had sex with a horse". Your SO is the only one taking a drink, again. Uncomfortable quiet laughter ensues. The third person says "I've never met Chris Hansen". Your SO drinks again. Everybody's looking at you and your date strangely. What do you say?
Nothing. Just let things unfold as they're already unfolding. It's out of my hands.
"Hahaha. He/she's such a kidder. Aren't you, sweetie?"
"He/she obviously doesn't understand the rules of this game"
"Don't look at me. I'm just as flabbergasted as you are. So, honey, how did you meet Chris Hansen exactly?"
Break up with him/her right there on the spot in front of everyone
See the fun my SO is having and start drinking at all the creepy questions, too
Excuse myself to go to the bathroom and secretly call 911 and report my SO
Crack up hysterically because I assume my SO is joking.
