This one beats them all and it’s going to make me laugh until tonight:
“I’ve been assigned to carry out a penetration test on a server you manage. The test will be performed from the outside, since the perimeter security needs to be assessed. In order to perform the test, I therefore ask you to disable any firewall, protection, blacklist. If any of these are in place, the server might not be reachable and could prevent the assessment.”
I had to read it three times just to make sure I’d understood it properly.
