What day is it?
Over breakfast one morning, a woman said to her husband, "I bet you don't know what day this is."
"Of course I do," he indignantly answered, getting up from the table and going out the door to the office.
At 10am, the doorbell rang. When the woman opened the door, she was handed a box containing a dozen long-stemmed red roses. At 1pm, a foil-wrapped, two-pound box of her favorite chocolates arrived. Later, a boutique delivered a designer dress.
The woman couldn't wait for her husband to come home. When he did, she exclaimed, "First the flowers, then the chocolates and then the dress! I've never had a more wonderful Groundhog Day in my life!"
