Yesterday, we shared a video of Peter Dinklage singing about how Tyrion Lannister has lasted so long in the series without getting killed. Turns out, Nikolaj Coster-Waldau a.k.a. Jamie Lannister also has a song up his sleeve (the longer one). But unlike his brother, he isn't bragging but instead trying to serenade his sister Cersei (it's perfectly normal in GRRM world).
Check it out.
