Here's one I've been using for a little while... usually after a next day opener to keep the conversation going.
> "Do you know how to make sushi?"
< "Yeah", "No", "Kind of" -- usually "kind of"
> "Do I need a roller? I'm trying to do it with my hands... my friends are laughing at me"
> "I'm kind of making sushi drumsticks"
> "Actually that's being kind... I'm making messed up balls of rice and seaweed with shrimp sticking out"
About 80% of the time I get a "sounds sexy", "i wish i was eating sushi right now"... and then of course it leads to lots of options:
> "fuck this... im going to get sushi at <place>; come"
> "come teach me"
Just thought I'd share.
