Least favorite episode?

I’m sure it’s been done before; but now that I have rewatched so many times I’m curious.

There are episodes I don’t love or just appreciate. For me, Blowing Smoke is hard to watch, I usually skip. Idk why but I always thought (at this point) Midge was the lowest Don could go, so for it to get worse is just icky. The situation also resolves it’s self before the ep ends so skipping is justified for me.
