John & Bill were fishing down by the Ohio River on different sides of the riverbank at night. John was catching a whole bunch of fish for his family, but Bill hadn't caught any and was frustrated and called out to John, "How come you've been catching all them there fish and I ain't caught a single one?"
John replied, " I don’t know.... why don’t ya come on over here?"
Bill replied, "I don’t know.... I don’t see a bridge, and their ain't no boat, and I don’t swim to well."
John picks up his flashlight, turns it on, and replies, " Why don’t you walk across this here beam of light?"
Bill was outraged and replied, "Do you think i’m stupid? When I get half way you'll turn it off!!!"
