A woman was helping her husband set up his new computer, and at the appropriate time in the process, told him he would now need to enter a password.
Something he would use to log-on.
Her husband was in a rather devilish 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 that he was keying in:
P...
E...
N...
I...
S...
His wife fell out of her chair laughing when the computer replied
***PASSWORD INVALID...........NOT LONG ENOUGH***
