I once received this e-mail from a posh girl's school:
"An e-mail addressed to you has been blocked by 'PornControl', due to its obscene content. The offending content was 'xxx'."
It turned out that my friend had
signed off with, "See you soon, Jenny. xxx"
(a) 'PornControl' (not its real name) was set not to protect the girls from the wicked outside world, but to protect the outside world from the obscene girls.
(b) If it detected an
obscenity in an e-mail, it kept
the e-mail and just sent the obscenity.
(c) There's nothing wrong with typing 'xxx'
Don't ya just love it?
