'Happy Anniversary Mom
and Dad,' gushed son number one .... 'Sorry I'm running late. I had an emergency
at the hospital with a patient, you know how it is, and I didn't have time to
get you a gift.'
 
'Not to worry,' said
the father. 'The important thing is that we're all together today.'
 
Son number two arrived
and announced, 'You and Mom look great, Dad. I just flew in from Los Angeles between
depositions and didn't have time to shop  for you.'

'It's nothing,' said
the father. 'We're glad you were able to come.'

Just then the daughter
arrived. 'Hello and happy anniversary! I'm sorry, but my boss is sending me out
of town and I was really busy packing so I didn't have time to get you
anything.'

After they had finished
dessert, the father said, 'There's something your  mother and I have wanted to
tell you for a long time. You see, we were very  poor. Despite this, we were
able to send each of you to college.  Throughout the years your mother and I
knew that we loved each other very much, but we just never found the time to get married.'
 
The
three children gasped and all said, 'You mean we're
bastards?'
 
'Yep,' said the father.
'And cheap ones too.'
