If you really want to screw with him, pretend you are interested and have him send the check. Basically, waste as much of his time as you can, while leading him on to believe you really want to sell him the item. Give him a fake address to send the check to so he doesn't know where you live. These guys are obviously scammers so have some fun with them and waste their time. As long as they are led to believe that you want to follow their terms, they will stay on the line. Finally, after they are frustrated about you never receiving the bogus money orders, tell them you sold the item to someone else from Nigeria!
