Just had an idea while I was dreaming, thought it might be worth a try to use irl, but it hasn't been tested yet.
What I'm thinking of doing is a mute opener, basically you're not allowed to talk for about a minute and the entire thing works with Kino and a sense of mystery.
The basis of the opener is kind of "wandering" up the the HB(Not a direct path), and waving, but leaving you're hand in a kind of stop sign motion. Once you get close to them, do the "hey you get something on your shirt" when they look down bring it up and tap there nose. Do something to show you're trying to laugh but don't actually make sound. Try to keep up the mute act for like 40-60 seconds, and then just blurt out talking.
It's not much of a seriose opener, but Good luck have fun.
