generic batman ripoff

I had discovered that fellow billionaire Bruce Wayne was batman and I wanted to do that too only I saw it more like a hobby and didn't go out much. I mostly used it as an excuse to build a secret mancave in my mansion, buy some fancy cars, and do parkour across the city for exercise. I "fought" against a villain that was one part Joker and one part Riddle called the Giggler. We "fought" by him leaving geocaches of jokes and puns that were clues to the next spot like a scavenger hunt. If i completed them all in a set time and found him he'd take me to lunch and if i didn't find him in time i'd take him to lunch.
