What is your least favorite episode?

It's a near perfect show - and we're always talking about that. But what is your least favorite episode?

This is my ultimate comfort show and I have it on in the background while I'm working and in the evening when I'm winding down (painting usually). I'm on what had to be my 6th rewatch/relisten.

I skip the Christmas episode with flashbacks. I can't stand a flashback - and seeing snips of the Rose's life before the motel is so depressing.
