In case you’re having trouble ID’ing the accents, the YouTube caption gives us the 411. “A group of foreigners. A cramped flat. A sitcom where worlds collide. Denmark, South Africa, Ireland, Canada, Dagenham… They’re not from around here, but that’s the least of their worries.” Especially when they find a gun on the doorstep.
Safety Nazi that I am, I would have preferred it if the Aussie had cleared the gun and insisted on muzzle discipline, but then it would have eliminated the punchline. Still, not entirely anti-gun and more than a bit funny. IMHO. Yes?
