Where's the punchline? What is the funny explanation of Alfred spending time in Arkham while being Bruce's butler?

Wtf?

There's a few threads of this already going, use the search function

i dont understand why his bio here was changed to include that. its clearly going to be revealed to be a lie. even batman pointed out at the end that it was "impossible, i can see the joker sitting right there."
