In the Dr. Ken episode ‘Ken’s Old Professor’, while Damona (Tisha Campbell Martin) considers breaking up with her boyfriend Eric, Ken (Ken Jeong) gets a visit from his old medical school professor, Dr. Donald Erwin. Dr. Erwin is there for a checkup and “picks up where he left off years ago by making his former student’s life a living hell.”
Dr. Donald Erwin is portrayed by Jonathan Banks. He’s known for his role as Mike Ehrmantraut on Better Call Saul and Breaking Bad, and on Community (Professor Buzz Hickey) with Ken Jeong, Wiseguy (Frank McPike), and Falcon Crest (Kolinski), among many others. Dr. Ken airs Fridays at 8:30pm on ABC.
