a real rib tickler...

One of my father's 'on the spur of the moment' jokes, while chatting with an online technician regarding a problem. I laughed and laughed about this one.

Technician - "Close all windows"

My father - "With the temperature we are having today I not only closed the windows but the doors too."

Technician - "I mean on the computer."

and people wonder where I get my sense of humour.
