Redneck joke.

There were three redneck who tended to hang together, Bubba Bo and Clem. One night, Clem didn't come home. Eventually his old lady got upset and called the cops. After a brief search, a body was found along the rail road tracks, shredded from the train.
Since Clem's old lady was very upset, the cops called on Bubba to ID the body. (Dental records were of no use, and all redneck DNA is the same), Bubba walked into the morgue, looked at the body and said "Its really mangled, turn him over." So the coroners staff obliged. Bubba took a good look at the ass end, then said, "Nope, that aint Clem."
The cops next turned to Bo. When He got to the morge, he too asked for hte body to be turned over, and again made a close inspection of the rectum.
"Naw," said Bo, "that shore aint Clem."
The coroner was baffled. Both rednecks had inspected only his butt, so he asked how Bo could be sure.
"Well," said Bo, "every time the three of us walked into the bar, some one would say, Look, there's Clem with the two assholes."
