The funniest part is not even the costume, it's how quickly the whole thing starts sounding normal.
You begin by laughing at a man with a bin on his head, then 30s later he's talking about affordable housing, local accountability & kebab prices, & then you realise British politics has accidentally produced satire with a better manifesto than Reform & Restore combined.
He's the joke candidate & at least knows he's doing satire, meanwhile the men in normal suits are running around with one policy hammer marked "migrants" and treating every national failure like a nail.
I like how the roadman intuitively understands that the way to get power is to establish a gendarmerie and clean up low level crime and she has no idea what he’s talking about
