Batman: Arkham Asylum Easter Egg - Scarecrow's Interview

After getting to Arkham Mansion and collecting at least one interview tape there, go to the character bios and listen to it.

It's for Scarecrow and features Arkham staff panicking over what seems like fear gas. The interesting part is the names of the two doctors, Dr. Murphy and Dr. Combs.

No doubt a reference to Cillian Murphy who played Scarecrow in Batman Begins and Jeffrey Combs who played him in The New Batman Animated Series!!
