Jamie Foxx or Doc Rivers?
On Tuesday's Tonight Show with Jimmy Fallon actor Jamie Foxx performed a spot on impersonation of Coach Doc Rivers.Fallon and Foxx were playing a game where they sing songs while impersonating other singers. After Fallon did a song as Bruce Springsteen he complained that he hurt his throat. That prompted Foxx to drop into his Doc Rivers voice.
I would encourage you to enjoy the entire video, however the Doc Rivers impression starts at the 5:43 mark.
