hehe...if you want to feed them a bunch of BS. I love this one:

If you find an Atheist in your neighborhood,
TELL A PARENT OR PASTOR RIGHT AWAY!
(so they can report them to the commitee on UnAmerican Activities I'm sure)

You may be moved to try and witness to
these poor lost souls yourself, however
AVOID TALKING TO THEM!
(they may tell you the truth!)
