A lady fixed her husband a special meal for his birthday. After dinner she fixed him a pitcher of martinis then poured him a drink. Then she left to pick up his favorite dessert from the local bakery.
When she returned from her errand she found her husband, drink in hand, prancing about the living room wearing her bra, panties and high heels.
"What is going on?" she exclaimed.
Her husband got a quizzical look on his face and said, "What? You asked what I wanted for my birthday and I told you. I wanted to eat, drink and... be Mary."
