The Nelson Twins

God love them, but these ‘garden gnome’ resembling identical twins from New South Wales really struggle to spin the gimmick out long enough for an entire show. It’s only 45 minutes long, and it has its own warm-up act – the expressionless stoner, Luke Heggie – but their watery gags on kiddie-fiddling and beer attract more groans than laughs.
