What have the romans ever done for us?

After watching a very bizarre film about the multiverse „Everything everywhere all at once“ we walked out of the cinema in a dazed and confused state only to find an even stranger spectacle outside the town hall: a man on a podium dressed in a plastic wrapper of a Union Jack, a burning royal cypher of Queen Elizabeth II, and four romans soldiers in an enclosure, one with a dogs fur on his head playing a large circular hunting horn. The only normal thing this evening was having a pizza and a beer (only one, honest).
