A man and a woman were asleep...
A man and a woman were asleep like two innocent babies.
Suddenly, at 3 o'clock in the morning, a loud noise came from outside. The woman, groggy and bewildered, jumped up from the bed and yelled at the man, "Holy crap! That must be my husband!"
So the man jumped out of the bed scared and naked and jumped out the window. He smashed himself on the ground, ran through a thorn bush and to his car as fast as he could go.
A few minutes later he returned and went up to the bedroom and screamed at the woman, "I AM your husband!"
The woman yelled back, "Yeah, then why were you running?"
