A man walks into a bar and yells “Bartender, give me twenty shots of your best single malt scotch!”

The bartender pours the shots and the man drinks them down one at a time, as fast as he can.

The bartender says “Wow, I never saw anyonebody drink that fast” The man replies by saying, “Well, you’d drink fast if you had what I have” The bartender says “Oh my god, what do you have??!!”

The man says “Fifty Cents.”
