Where do Redheaded Babies Come From?

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.'
