Justin Timberlake makes fun of John Mayer on Jimmy Fallon's new late night talk show and man does he do an amazing job.
Justin Timberlake is becoming somewhat of a comedic genius and his rendition of "Daughters" is on the money. John Mayer hopefully has a sense of humor about all this and doesn't start ranting and raving on his blog about it.
Oh, and Justin Timberlake also kills it in an impression of Michael McDonald. The magic starts at about 6:15.
