A friend with whom I have attended and exhibited at gun shows since college days has a line for the "I have one of those" guys. He puts a $100 bill on the table and says, "I'd really like to see that. We'll be here all weekend. Bring it in to show it to us and the $100 is yours." He is still using the same $100 bill thirty some years later. Maybe he will post and share some of the stories about "The Bill".
