Wedding Gift

Martha had a wedding to go to and needed a wedding gift, but she procrastinated and ended up having to come up with something a couple days before the wedding.
She thought about it and finally decided, “Aha, I have that monogrammed silver tray from my wedding that I never use. I’ll just take it to a silversmith and have him remove my monogram and put hers on it. Voila, one cheap wedding present.”
Happy with her idea, she took it to the silversmith and asked him to remove her monogram and put the new one on.
The silversmith took a look at the tray, shook his head, and said, “I’m sorry, but I can’t help you. This can only be done so many times!”
