I know this is probably an old one, but it still makes me laugh every time I read it!
A female computer consultant was helping a smug male set
up his computer.
She asked him what word he would like to use as a password
to log in with.
Wanting to embarrass the female, he told her to enter "*****".
Without blinking or saying a word, she entered the password.
She almost died laughing at the computer's response:
PASSWORD REJECTED.NOT LONG ENOUGH.
