Just wanted to alert people that William Schallert, aka Nilz Baris of The Trouble With Tribbles (and the father on the Patty Duke Show), guested on Medium last night. Just a small part--he was this old rich guy murdered in the opening scene. His hair is very white but his face is the same. I looked for his name in the opening guest star credits and sure enough, it was there. Nice to see he's still acting...

I just saw him. "J. Donald Kessinger" got even less respect than Nilz Baris! At least the undersecretary didn't get killed. Honestly, I would not have recognized him at all if you hadn't pointed it out. More power to him to still be acting at age 87; he was actually pretty comical.
