An ounce of Silver walks into a Bar

The bartender says "I didn't know Silver had legs"
Silver says "I'm from the future"
The bartender says "that's wicked, what kind of drink would you like?"
Silver says "a Blue Kamikaze, a Long Island iced tea and a Virgin Cuba Libre"
The bartender says "by the way, do you know when and how I will die"
Silver says "Yes the matter a fact I do, one of these drinks will be your demise"
The bartender awkwardly smiles
