Grandpa Ho, challenged

Grandpa Ho, a Vietnamese man in his 80s who breakdances: small and wiry, wispy long white goatee and eyebrows, bald on top, big grin with a gold tooth, wearing a shiny retro purple and lime tracksuit, white high-top sneakers. In a neon-lit underground breakdance battle, a teenager points at him across the circle; the push lands on his face as his eyebrows go up and his gold tooth flashes in a grin.
