Sleep Running

A man and a woman were fast asleep in bed. Suddenly, at 4 O'clock in the morning,  A resounding noise came from outside.  The woman, sort of bewildered, Jumps up from the bed and yells at the man  "Oh No!, that must be my husband!"  The man quickly got out of bed, panicked and naked. He jumped out the window  like a crazy man, smashed on the ground, picked himself up and went straight  through a thorn bush, then he stood up and started to run as fast as he could  to his car...  A few minutes later the door opens and the man is standing at it, panting hard,  with dirt and scratches all over him. He yells: "I'M your husband, you mad cow!" And the woman answers: "Oh, yeah? And why were you running, you bastard?!?"
