magic coffee 

decaf coffee misrepresented as the real stuff. Often done in the catering industry, where both both regular and decaf coffee are actually decaf. the waiter will often serve coffee, return the the kitchen and emerge with the same pot of coffee for the guests who requested decaf (because it actually is decaf). Some waiters will say an incantation over the pot in the kitchen (converting it to either reg or decaf)

Waiter 1: Are we doing regular AND decaf coffee this evening

Waiter 2: Nope, just magic coffee today.
