Persistent, these devils!

Jehovah's Witnesses returned this morning. Three of them, this time. All women.

old_cutter_john:  Who's there?
                                                  [silence]
old_cutter_john:  Who's there?
Jehova's Witness:              We're known as Jehovah's Witnesses.
old_cutter_john:  No, no. I spent an hour on that yesterday, and two more hours
                                                  in the past two weeks, and that's enough.
Jehova's Witness:              Have an nice day.
