VALENTINE CARDS

A woman walks into a post office one day and sees
a middle-aged, balding man standing at the counter
methodically placing "Love" stamps on bright pink envelopes. 
He then takes out a perfume bottle and
starts spraying scent all over them.
 

Her curiosity getting the better of her, she goes up to
the balding man and asks him what he is doing.

The man says, "I'm sending out
1,000 Valentine cards signed, 'Guess who?'"

"But why?" asks the woman.

"I'm a divorce lawyer," the man replies.
