A wife was in bed with her lover when she heard her husband’s key in the door.
“Stay where you are,” she said.
“He’s so drunk he won’t even notice you’re in bed with me.”
The husband lurched into bed, but a few minutes later, through a drunken haze, he saw six feet sticking out at the end of the bed. He turned to his wife:
“You’re so drunk you miscounted,” said the wife.
The husband climbed out of bed and counted.
One, two, three, four, you’re right.
