Carpet isntalled with nails?

Kinda reminds me of the old joke where the old lady complained that her husband's toupe kept sliding off while he was laid out in the funeral parlor before the viewing. Whatever the funeral director did was successful and the toupe stayed on the deceased's head for the entire time. The old woman was so grateful that she wanted to pay the funeral director for the fix. The man kept demuring with each request for him to take more money for the repair. He finally told her, "Lady, it was not such a big deal; how much could a coupla nails cost?"
