"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!"
