"New Grog"
The New Grog machine is a reference to the Grog machine in the Monkey Island series, which was a parody of Coke machines. New Grog is a parody of New Coke, the failed attempt by Coca-Cola to introduce a new cola with a different formula from regular Coke. It is also a play on the fact that this is a new Grog machine in comparison to the old one found in the Monkey Island series.
