This music parody video from wekejay of Justin Timberlake's "Suit and Tie" has a ton of good in it: a spot-on Tony Stark, an excellent merging of the set from the original Timberlake video and the Stark Expo from Iron Man 2, Rhodey's guest rap...
It's not just a clever video, the lyrics are pretty great, too. C'mon, tell me that "Let me blow up a few things" isn't a vast improvement over "Let me show you a few things." Plus, where JT just repeats that phrase ad nauseum, Tony also gives us this question for the Mandarin: "What's the deal with those weird rings?"
"Suits That Fly" was directed by Wesley Freitas and Jonathan Bruno. The rest of the credits (and the full lyrics) can be found in the about section on youtube.
