This is a filler episode. It has about 5 minutes of new material, the rest is clips from earlier episodes. I genuinely don't understand why show runners think this kind of thing is ok, it's a total waste of time, if I'm ever president the first thing I'm going to do is outlaw this kind of episode with an executive order.
Seriously, you can skip this episode and not miss anything at all.
