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
(Obviously the true leftist answer is all of them)
sometimes they get me good, I'll be about to do something that will make my hands messy or just occupied for a while, take a quick look at how much of the episode is left and think "ah plenty of time", then my hands are covered in paint or grease a scant few minutes later and the storytime starts
