Because they just appeared unexpectedly, seemingly coming out of nowhere, this makes me think of a scene from a "Pink Panther" movie or the old "Get Smart" TV show. I can just see Clouseau or Max following someone up this alley and trying to get by these guys as they keep pushing him back! I ended up seeing them later in the Grand Plaz where they were performing for some official EU gathering. I'll post those pics later.
