You laughin' at me? Let's hope that's the case when revered Oscar-winner Robert DeNiro returns to host SNL for his third time, kicking off three weeks of new episodes. (DeNiro's Little Fockers, the third film in the Meet the Parents series, opens Dec. 22.) Musical guest is Diddy-Dirty Money, a group comprised of Sean "Diddy" Combs, Kalenna Harper and Dawn Richard.
