Dr. Actor is a minor character who first appeared in the episode The Lost Mattress. He also made an appearance in the episode All That Glitters, when it was revealed that he was simply an actor doing research for a part. He once auditioned for a play or, most likely, a soap opera (possibly a Soap Opera Channel production), but he unfortunately did not get the call-back. He then became a full-time doctor.
The replacement doctor is purple and wears a doctor uniform. He has a sad looking face and a blue tie.
