“If you saw the episode and you say, ‘There’s a lot of them!’, the script had probably twice as many,” Silicon Valley executive producer Mike Judge told Entertainment Weekly. “And then T.J. came in with, oh my God, so many. That’s where T.J. lives, in those kind of things, and he’s so good at it.”

The outtakes are a funny ode to the workplace generational divide, but they’re also a fascinating look at how comedies like Silicon Valley are made. No doubt that some of the insults were written in advance, but many appear to be improvised by Miller on the spot. The show filmed all of them, and later picked out the best ones during the editing process, and put those into the episode that aired on HBO.

So, to all employees roughly older than 34 who feel culturally inharmonious with your younger colleagues—next time there’s a work dinner outing, don’t order the deviled eggs, lest you be labeled as “an old.”
