"Gentlemen. Ladies. I know you're asking yourselves how tonight can possibly get any better than this. Well, I think I have just the thing."
You take a case from the back and open it to the audience.
"This is our most priceless artifact, dating back circa 1934. A Gibson Super 400, in the same condition it was manufactured in. 'The biggest, fanciest, and most expensive archtop ever built.' Every part of the instrument but the strings were manufactured and engraved by hand. The varnished maple body gives it a distinct sound. This is one of the last 400's left. It's safe to say this could be worth upwards of fifty million."
You shed a tear of joy just by holding it, as if you had reunited with an old friend.
"We'll start at four hundred boonbucks."
