A boy goes to the
drug store with
his dad and sees
the condom
display.
Boy: "Dad, why do
they do packs of
one condom?"
Dad: "Those are
for the high-
schoolers for
Friday nights."
Boy: "So, why do
they make packs
of three?"
Dad: "For the
college guys for
Friday, Saturday
and Sunday
nights."
Boy: "Then why do
they make packs
of 12?"
Dad: "Those are
for married
couples -- you
know, January,
February, March."
