Let me guess: he interjected at one point during the interview to say how great Steven Spielberg is, how much Spielberg's given to all of us, and how great Tom Cruise feels knowing he "grew up" on Spielberg (despite the fact that they're nearly the same age :|)
Oh, and I'm sure he did his Donald Duck impression.
Interviewer: Hey, so I've heard that you do impressions.
Cruise: oh, no, no, no....
Interviewer: Oh, come on...do one *like you instructed your publicisist to tell me, jackass*
Cruise: Let's talk about the movie...Spielberg
Interviewer: *omg* crowd do you want to hear Cruise do an impress--
*Before the interviewer finishes talking, Cruise starts doing a Donald Duck impression, like he's wanted to do all along*
Ugh. Almost as bad as those douchebags that are like "What!? You got a rare clip of me doing an embarassing commercial as a child? How ever did you find that?" Gee, maybe they found it in the package you sent to them via Fed Ex.
