Fire in the Furnace
A 75 year-old Englishman, whose hair was completely white, married a 20-year Swedish girl and she got pregnant soon afterwards.
Nine months later, the Englishman walked into the maternity ward and asked the nurse on duty, “How did my wife do?”
The nurse replied, “She gave birth to twin boys.”
He chuckled, “Heh, heh, heh, well, I guess that goes to show even when there’s snow on the roof, there can still be fire in the furnace.”
The nurse commented, “Well then, you better change filters. Both your boys are black!”
