walk-up lines

just back from a week of mission.
among other things, this involved lots of door-knocking and walk-up evangelism.
doing this sort of thing at a university campus, you start getting an idea of what works and what doesn't, but in a diverse suburb like Kingsford there never seemed to be a clear tack to take.
one that we started using was:

Hi. We're not Jehovah's Witnesses or Mormons; we're just going around asking people about Jesus.

this seemed to get us a little further into the conversation than otherwise, particularly with one Greek Orthodox lady - who about 5 minutes in, and after said introduction, asked whether we were JW's!
another line we tried was hi, we're giving away FREE Bibles, which worked for one person.
for some overseas students, they had actually never even heard the name of Jesus. which drives home the need to continue talking about him to people from all nations. and reminds us to give thanks for his patience:

The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance. (2 Peter 3:9)

have you got a good line for talking to strangers about Jesus?
