My favorite Superbowl moment. Here is the back story:

The spot was shot last Tuesday afternoon, under the strictest of secrecy which involved both Mr. Leno and Ms. Winfrey flying in surreptitiously to New York, and arriving incognito at the theater, while Mr. Letterman was in the midst of taping his show for that night. It also involved Jay wearing a disguise: hooded sweatshirt, glasses and faux mustache. If you happened to be on Broadway between 53rd and 54th street last Tuesday about 4:15, you might have seen a man fitting that description slip into the theater by a small entrance under the marquee.
