THE OLD ENGINE
----------------------------
A 78 yrs old white man who married a beautiful young woman (28 yrs old).
In the hospital when his young wife delivered the first baby...
Doctor: "Congratulations, you got a 3.5 kg baby boy..."
The Old man (smile): "My old engine still work well."
A year later the woman delivered the second baby...
Doctor : "Congratulations, you got a 3.0 kg baby girl..."
The Old Man (still in his big smile) : "Hmmm my old engine is still good !!!"
After 1 and half year later the woman delivered the 3rd baby... still in the same hospital and the same doctor ...
Doctor: "Congratulations, this time is a boy again... only 3.0 kg."
..
"Wow...my old engine still doing good... I can't believe..." said the old white man still in his big smile...
Doctor : "Yes... but i think you better change your engine oil... because this time the baby is black..."
