Wedding present

A friend of mine claims this happened to a friend of hers:

She had a wedding to go to, and needed a wedding gift. Aha, thought she, 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.

So 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,

"Sorry Lady, you can only do this so many times!"
