IS IT MINE?

AFTER THEIR BABY WAS BORN,

THE PANICKED FATHER

WENT TO SEE THE OBSTETRICIAN.

"DOCTOR," THE MAN SAID,

"I DON'T MIND TELLING YOU,

BUT I'M A LITTLE UPSET

BECAUSE MY DAUGHTER

HAS RED HAIR.

SHE CAN'T POSSIBLY BE MINE!" 

"NONSENSE," THE DOCTOR SAID.

"EVEN THOUGH YOU AND YOUR WIFE

BOTH HAVE BLACK HAIR,

ONE OF YOUR ANCESTORS

MAY HAVE CONTRIBUTED RED HAIR

TO THE GENE POOL." 

"IT ISN'T POSSIBLE,"

THE MAN INSISTED.

"THIS CAN'T BE,

OUR FAMILIES ON BOTH SIDES

HAD JET-BLACK HAIR

FOR GENERATIONS." 

"WELL," SAID THE DOCTOR,

"LET ME ASK YOU THIS.

HOW OFTEN DO YOU HAVE SEX?" 

THE MAN SEEMED A BIT ASHAMED.

"I'VE BEEN WORKING VERY HARD

FOR THE PAST YEAR.

WE ONLY MADE LOVE ONCE OR

TWICE EVERY FEW MONTHS." 

"WELL, THERE YOU HAVE IT!"

THE DOCTOR SAID CONFIDENTLY. 

"IT'S RUST."
