Manager: Do you know anything about this fax-machine?
Staff: A little. What’s wrong sir?
Manager: Well, I sent a fax, and the recipient called back to say all she received was a blank page. I tried it again, and the same thing happened.
Staff: How did you load the sheet?
Manager: I didn’t want anyone else to read it by accident, so I folded it so only the recipient would open it and read it.
