Having fun with a Scammer

I have a bike for sale and was contacted by one of "those" with the "bank check" etc. I emailed back I would be glad to deal with him but only if the check was delivered by a 28 year old red-headed virgin and an equal amount of gold bullion to hold as a security deposit. He wrote back wanting to make arrangements for the check exchange. My reply was to call him a stupid ( expletive deleted, begins with "M" ).
