But be reasonable

In the middle of night, a wife woke her husband, "Darling, it's so cold!"
The husband jumped out of the bed, brought one more blanket from a closet and
carefully tucked it around his wife's body. After a while, the wife woke him
once again, "My dear, it's so hot here." The husband jumped out of bed and
rushed to open a window. In a few minutes the wife woke him one more time and
said, "My love, I want a man."
"But be reasonable," the husband said. "Where can I find a man in the middle
of night?"
