The 'Perfect Password'
A woman was helping her husband set up his computer, and at the appropriate point in the process, the computer advised him that he would now need to enter a password. Something he will use to log on. The husband was in a rather amorous mood and figured he would try for the shock effect to bring this to his wife's attention. So, when the computer asked him to enter his password, he made it plainly obvious to his wife what he was entering by stating each letter out loud as he typed:P...E...N...I...S His wife fell off her chair laughing when the computer replied: **** PASSWORD REJECTED. NOT LONG ENOUGH***
