Need help finding an episode!

There’s an episode where in the story there is a kid character and Hunter gives it the most monotone flat voice and Isaiah does not appreciate this and says something like “You really gonna go with that one?” and Hunter continues that voice throughout the video. I don’t even remember anything else from the story but that bit. I think it was a mother talking to a son in that scene but can’t remember if it was a grabbag ep or something longer.

Anyone know what I’m talking about?
