Which episodes do you love a bit less than the others, i.e., which ones do you skip on a rewatch?

I skip the one with the rat infestation in Poplar, because I hate rats. I also skip the one with Mrs. Chen, the Chinese grandmother who insists on keeping her daughter in law and baby very warm for 40 days post partum... the hot stuffy apartment with a fire burning in the middle of summer looks so infuriatingly unpleasant that I just skip the whole episode.

Which episodes are you inclined to skip and why?
