For me it has to be the Berlin live episode and in top spot the live DnD episode, which I literally had to turn off after about 15 mins because it was too embarrassing. I can't imagine what being in the audience must have been like, lmao

I could see it being its own show or something, but it's like opening a box of cookies and discovering it's been replaced with celery when I see "new Chapo episode" then read the description and it's a whole episode where they dunk on Avengers 1,937,362
