Arthur:
How are you feeling?

Alfred:
Dude, what happened last night?
I think my arm's broken, and my car is wrecked!!

Arthur:
Well...you were so drunk that you climbed to the top of your garage.
Then you started yelling,
"Nanananana BATMAN!!!"
Then jumped off and landed on your car.

Alfred:
And you didn't take me to the hospital?!

Arthur:
I was too busy laughing.
