The Fuzzy Navel was a two-ingredient drink that became a staple in the 1980s. This stepped-up version adds vodka to the original cocktail's mixture of orange juice and peach schnapps(liqueur), making it a much more potent drink. 

Because it is so simple, it's perfect for riffing. For a more complex version, you can use orange-flavored vodka. This drink is also ideal for making a punch bowl by sizing up all measurements.
