One Sunday, one of the preachers didn't show up; the other preacher found him walking to church an hour or so later. The preacher on the bike asked the preacher walking, "Preach, where's your bike?" The walking preacher replied, "I think someone in my congregation stole my bike."
The preacher on the bike came up with an idea:
"When you're preaching your sermon today, preach the Ten Commandments, that way whoever stole your bike will feel guilty when you get to the one about 'Thou Shalt Not Steal' and return your bike."
The next Sunday both preachers were riding their bikes again.
"Well, did you do like I suggested and preach the Ten Commandments?"
"Yeah, and when I got to the one about 'Thou Shalt Not Commit Adultery,' I remembered where I left my bike..."
