holds the phone

I'm trying to find a severely hard sketch/improv show, I think someone linked an episode on here? It's something like "The Most Uncomfortable..." or Worst Improv or somesuch, and the improv prompts are extremely ornate and hyper-specific and crafted to be a kind of comedian's hell, as well as for the audience. It was over an hour long, possibly Australian?? I can remember only barest moments and nothing's turning up in web results. The main scenario was the 'guests at a dinner party' routine.
