Well just saw a video here:
Search youtube for: Russian World Record (touch a 1000 boobs) [Part 1] (Can't post the link to the video)
I think it would make a simple opener and you can also add a line to say "Hey we're going to need you name and number just incase guiness wants to contact you"
You will need:
Smiles, Eye contact, simple neat dressing and good hygiene
As you can see from the video, Some kiss him some embrace the touch, some smile and so forth.
