Alright. I'm tearing my hair out on this one. I need to find this old SFM video series.
It was about the civil protection forces in a psuedo Half Life 2 universe, sort of like the Civil Protection series.
One of the characters was a unit with a bucket on his head, and in one episode he was stuck on a barnacle. In one episode, they were trying to get someone for insurance fraud. The channel also has a random video of one of the doctor, I think, characters playing a piano. It had a load of custom models in it. There was also an episode with someone asking for directions to a garden party.
It was a documentary style series. I really want to re-watch it.
