A kid calls the help desk to complain about
computer problem

kid: when i type my
computer password,
it just
shows star star star
what is that joke?
.......Help Desk: Dear kid those stars are to protect you,
so that the person standing behind cant read your password

but stars appear even when there is no one standing behind me ;-)
