A female secretary was helping her new boss set up his computer and asked him what word he would like to use as a password to log in with.

Wanting to embarrass his new secretary a bit and let her know where they stood, he smugly told her to enter 'penis.'

Without blinking or saying a word, she entered the password.

She then almost died laughing at the computer's response:

PASSWORD REJECTED. NOT LONG ENOUGH!
