In the movie Batman and Robin, Poison Ivy had drugged an entire room of men with a chemical pheromone that made them all besotted with the villain. The Caped Crusader and the Boy Wonder get into a bidding war to win a date with Ivy. And that’s when Batman takes out the Bat-Credit Card. A concept that is so hilarious, especially if you imagine the Dark Knight get a cup of coffee while looking out from Gotham and using the card cause he just didn’t have change.
So Batman may have every kind of vehicle, from the Batmobile to the Bat-plane. But sometimes even the Dark Knight has to put aside his pride and put on a pair of roller-skates to catch a very fast moving bad guy. That seems logical enough until you see Batman and Robin cruising through the Gotham streets in skates. Hard to keep a hardcore facade.
