1. Who Shot JR? (Dallas)
2. Z’ha’dum (Babylon 5)
3. City on the Edge of Forever (Star Trek)
Runners up—One Son (X-Files), the last Newhart (Second Series), final episode of Mad Men, first episode of The Shield, White Rabbit (Law and Order S5 E5)
I had forgotten about “Newhart”. The episode where the pretty young blonde girl meets Larry, Daryl and Daryl in the woods was hilarious.
