FATHER:   "When you go back to your Mom's tonight,
give her this envelope and tell her that since you are
now 18, this is the LAST check she'll ever see from
me for child support.  Then, stand back and watch
the expression on her face."


DAUGHTER:  "O.K."


Later.......


DAUGHTER:  "Mom, Dad asked me to give you this
envelope. He said to tell you that since I'm now 18,
this is the LAST child support payment he'll ever
have to make to you.  Now I'm supposed to stand
back and watch the expression on your face."


MOTHER:  "Next time you visit your father, tell him
that after 18 years I have decided to inform him
that he's not your father. Then, stand back and
watch the expression on HIS face."
