Adam and Eve
After Adam stayed out late a few nights, Eve became suspicious.
"You're running around with another woman, admit it !" she demanded.
"What other woman?" Adam shot back.
"You're the only one here."
That night, Adam was fast asleep when he was woken up by Eve,
poking him in the chest.
Adam asked, "Eve, what are you doing ?"
"Counting your ribs."
