The Misadventures of Batman and Robin

The Joker: Part One

So it was just in average day in Gotham: Citizens doing their jobs, policemen buying donuts, and Robin and I were playing video games on our PBox 1080. I was just ahead of John by 1 kill when the phone rang from a mysterious number. I paused the game and walked over to answer it. "The Batcave this is Batman speaking."
"Ah yes, Batman. I've been looking for your phone number... I had it until The Riddler ripped up my phone book..."
The Joker answered.
"Okay so I know your like the biggest villain in Gotham, and I should be concerned why your not locked up or why your calling ME, but I'm more concerned why you have a phone book. Get with the times, man." I replied. Maybe he doesn't know how to use
A phone....
"Well I can't afford a cellular phone so I have to put the contacts in a phone book. I can't memorize everyone's phone number... After all I do need a bit of time to plan out my crimes, don't ya know." Joker says.
"Well when's your birthday, I could get you a pho-" Robin interrupts me before I could finish.
"Batman! We have a criminal on the phone! Track where he's calling from and then we can capture him!" Robin has a point. After all, I can't afford a new cell phone.
"You're right, Robin. Joker, we're coming for you." I hang up the phone.
"TO THE BATMOBILE!" I shout.
