The best NBA impersonator did perfect Nowitzki

Brandon Armstrong, known for his hilarious impersonations of NBA players, pretty much nailed his Dirk Nowitzki.

He does the future Hall of Famer's wincing face, his iconic one-legged step-back and his three-point celebration, and even reenacts this C.J. McCollum play that completely fooled the Dallas Mavericks star.

It even got the seal of approval of the man himself with a retweet, so you know Nowitzki thinks it's pretty good.
