The next time you fancy getting a workout in Dublin city centre, you could try this...and get arrested probably. 

Daragh O'Connor and Ciarán Ó Scanlain are two guys with serious parkour/free-running skills, and recently they filmed themselves performing some stunts in Dublin city centre. The video features the guys climbing and balancing on some of the city's most famous landmarks, including the Ha'penny Bridge and Trinity College. 

Of course, we have to add that you definitely shouldn't try this at home or outside your home. Just don't try this, as the Gardaí will be on to you, just like they were for these guys.
