Ginger Ale: Batman’s Secret Weapon
One of the many ways that Bruce Wayne created the illusion of being a frivolous playboy and not a terrifying night avenger was by lolling around and drinking a lot of champagne -- except that it wasn't actually champagne, but ginger ale. This was so that he could retain his cat-like (or BAT-LIKE) reflexes if a supervillain attacked the party and he had to change into Batman, which he usually did.
Dinosaur Comics explores this wonderful deception with a comic that leaves me wondering why more rappers haven't explored the "Bruce Wayne / champagne" rhyming pair. It's just asking for it.
