VIDEO: Two lads turn Dublin city into a gravity-defying giant playground

Your arms will be aching after just watching this video.

Oisin Carroll and Daragh O'Connor have made a video in which Daragh and another guy, Ciarán Ó Scanlain, show us "how to have fun and keep fit in your city".

From climbing statues to swinging across the Liffey, they really make us envy their upper body strength.
