"Blasphemy" joke

A farmer in Alabama was driving across a bridge in his pickup
truck when he noticed a man standing on the rail of the bridge
ready to jump to his death in the river below.
The man stopped his truck, ran up to the man, and said, "Hey
fellow, why are you doing this?" The man replied, "Well, I
have nothing to live for."
The Alabama man replied, "Well, think of your wife and
children!" The jumper replied, "I have no wife or children."
The Alabama man then said, "Well, then think of your mother
and father!" The man replied, "Mom and Dad passed on many
years back."
The Alabama man then said, "Well, think of General
Robert E. Lee!" The would-be jumper replied, "Who?"
With that the Alabama man said, "Jump you stupid Yankee, jump!"
