In what seems to be almost an every two or three month event, Justin Timberlake was on Jimmy Fallon last night and once again they continued what at some point is going to be enough material to actually sell, their third installment in the history of rap. Justin Timberlake to me is really hit or miss as an actor, but he is really good at this type of thing and should really think about being on SNL full-time for a year or two to really get some training and practice. He is at his best there and here, but not so much movies. The worst part of Bad Teacher? Justin Timberlake.
