I've just had the "Computer" bloke ring me...
"Hello, is that Mrs Day, I'm ringing about your broken computer"
Me in the gruffest voice I can do "Yeah, this is Mrs Day, I've been waiting for you!"
"Good,madam, could you please switch your computer on?
"Yep, give me a minute Duck!"
Meanwhile I've got my high pitched dog whistle and blew it down the phone then hung up...

A minute later he rings back...
"Mrs Day, what happened there?"
"Well, I switched the 'puter on and it keeps making a high pitched whistling noise... (then I blew it again down the phone) see, it's done it again, can you fix it?"
"Yes madam I can...." (I interrupted with a really prolonged whistle blow) Phone line goes dead
