Unshaved sheep

"So how do you get to sleep?"

"Well I put my head down and within seconds I'm counting sheep."

"And what about you madam?"

"I have a cup of cocoa, put my head down and before I realise it, i'm dreaming of knitting odd socks."

"Wonderful.  Excuse me Sir, how do you get to sleep?"

"Well, first of all i put in my ear plugs, then i cover them with dense cotton wool, then a thick towel, then i put on headphones and turn the volume up so i can just about hear it."

"Isn't that a bit extreme?"

"Not as extreme as what i'm doing to those bloody sheep!"
