Postal joke

I wonder, this window is closed well, where did you get the funny connotation jokes?

Playing mobile phone in bed at night, my wife suddenly said to me, "Husband, I'm cold." I immediately pulled the quilt to cover her, then hugged my wife and said, "It's not cold now." Wife: "I still feel cold and windy." I wondered, "This window is well closed. Where does the wind come from? " The wife whispered, "There is no basis."
