The corner shop baker was a true artist when it came to making birthday cakes. One customer asked him,
"Can you make a birthday cake for my wife, she's an optician?"
He agreed and produced a birthday cake in the perfect detail of a winking eye. His next customer said,
"Can you make a birthday cake for my husband, he's a dentist."
He agreed and produced a cake in the shape of an open mouth, including the teeth and tongue. At that moment another customer began to leave his shop, when the baker asked,
"Can I help you?" The lady turned and said, "No, I don't think so. It's my husband birthday today, but he's a proctologist."
