A married man and his secretary were having a torrid affair.  One afternoon
they couldn't contain their passion, so they rushed over to her place where
they spent the afternoon making passionate love.

When they were finished they fell asleep and didn't wake up till 8 o'clock.
They got dressed quickly when the man told his secretary to take his shoes
outside and rub them on the lawn.  Bewildered, she did as he asked (thinking
him pretty weird).  The man finally got home and his wife met him at the door.
Upset, she asked where he'd been.

The man replied, "I cannot tell a lie.  My secretary and I are having an
affair.  Today we left work early, went to her place, spent the afternoon
making love then fell asleep.  That's why I'm late."

The wife looked at him, took notice of his shoes and said, "I see those grass
stains on your shoes.  You've been playing golf again, haven't you?"
