You mean that the pie was Martha's idea and that the K-Mart representatives were not expecting a bill of any kind? Did she bill them individually or send the bill to the company? Was she willing to accept payment in cash? Did she collect state sales tax on the sale of the pie? Did she make a profit on the pie and did she report the income?
If it is as you say, then we will definitely be seeing more of this when the inevitable TV movies come out.
I thought they already did -- the hit piece starring what's-her-name from Moonlighting.
