Tongue Part Way in Cheek
from: Megalith Electronics
to: Mr. Pat Pendng
Dear Sir/Madam:
Thank you for your suggestion that we should buy your invention for Synchornous Anachronistic Wobbly Widget. However, we at Megalith have the greatest scientific and engineering minds in the industry, and if your idea had any merit, we would hold patents for it already.
Thank you again for your interest. We value you as a potential customer.
Randy Sparks, Vice President Engineering
