Browsing the costume stacks, John decided to wear a wolf costume. "The changing rooms are over there. Your wife is already getting changed."
"What costume did she pick?" asked John.
"She wanted it to be a suprise." replied the assistant.
John took the wolf costume into the changing room and tried it on. A few seconds after doing up the zipper he felt a tingle and instantly it felt like the furred costume actually was his skin. He felt for the zipper but discovered it had vanished.
Exiting the booth, he went up to the assistant. "The costume's grown onto me!" he said.
"Don't worry, we can easily remove it for when you go home. You can even remove or exchange it now if you want, before you leave the shop."
"No, I'll keep it." said John "Where's my wife?"
"Still in the changing room. She'll be coming out in a moment."
