This was voted the funniest joke in the mission over the last twelve months:

A non-denominational church was about to begin their services when the devil suddenly appeared in his vilest form screeching obscenities and threatening the very souls of the parishioners.  Everyone in the congregation fled leaving the chapel empty except for one elderly man sitting in the  front pew.  The devil cussed and harassed the old guy but to no avail--he just calmly sat there with a nearly amused look on his face.  Finally, the devil said, "Do you know who I am?"  "Yep."  "Then why aren't you afraid of me?"  The old fellow looked at Satan and grinned victoriously, "Cause I've been married to your sister for forty-four years!"
