2nd Hillbilly says: "That's nothin'! My wife is so stupid, she bought one of   them new fangled warshin ' machines!"

2nd Hillbilly says: "'Cause we ain't got no plummin'!"

3rd Hillbilly says: "That ain't nuthin'! My wife is dumber than both yer wifes put together! I was going through her purse the other day lookin' fer some change, and I found 6 condoms in thar."
