Hillbilly Ma says to her son,

"Jethro, I need you to fix the outhouse."

"What fer ma?"

"Jis go 'n hava look."

So Jethro walks out to the outhouse, opens the door, and looks, "I don't see nothin wrong here ma," he says.

"Look closer," says Ma. Jethro moves into the outhouse.

"Still don't see nuthin," he says.

"Stick yer head in the hole."

"But, Ma."

"Jis do it." Of course Jethro knows better than to disobey his ma, so he sticks his head into the hole.

Then he hollers, "Oww, Ma, my beard's stuck."

"Aggravating isn't it?"
