3 big rednecks
A guy in a bar leans over to the guy next to him and says, "Wanna hear a 'redneck' joke?" The guy beside him stiffens.
"Before you start, buddy, I think you oughta know something: I'm 6' 2" tall, weigh 200 pounds and I was born and raised a redneck. This ol' boy sittin' next to me is 6' 4", 225 and a redneck through and through. And that redneck sittin' next to him is better'n 6' 6", 275. Now, sonny-do you still want to tell your little joke?"
To which the first guy replies, "Nah. I'm glad you told me. I'd hate to have to explain it three times!"
