Hooray, we’re now almost up to date! Welcome to day 11 of The Edge‘s 2011 advent calendar. Today’s video is one I’ve seen making its rounds on Facebook, and it really is quite entertaining. Now, please don’t be put off by the fact that it features a boy who a writer for The Edge recently described as “the spawn of Satan”, Justin Bieber — it is the other fellow who is important. Impersonations are usually pretty awful, but this guy is incredible at nailing the voices of many of the biggest names in film, music and television, including Will Smith, Eddie Murphy and… Stewie Griffin? It has to be seen to be believed.
