"Unfortunately, this isn't a joke."

Jonah Hill should be having a great week! Jonah Hill is not having a great week. The two-time Academy Award nominee should be giddily promoting his surefire hit sequel, '22 Jump Street' on the late-night talk show circuit! The one-time 'Superbad' star instead kicked off his tour by turning up 'The Tonight Show' with one hell of an apology, a very necessary one after a paparazzi video hit the web earlier this week, showing an obviously angry Hill yelling a charged epithet at a photographer.

Hill's apology and comments on the matter are unexpectedly moving, serious and sincere. You could hear a pin drop in Jimmy Fallon's studio during his nearly three-minute speech. At one point, he got choked up. We did, too.
