"The Hardest Button to Button" and "Fell in Love With a Girl" by the White Stripes, definitely. And "The Denial Twist." Basically any Gondry-directed video, actually.
I like most of the White Stripes' other video, too. "Seven Nation Army"...that Coke commercial Jack did...I don't really like "Blue Orchid" but it gets an honorable mention because it made Jack White looks like Jack Sparrow. <3 <3
Garbage has a history of great videos, as well - including my all-time favorite video, "The World is Not Enough." I also really like "Special" and "Tell Me Where It Hurts," just because it'll probably be their last.
I think my second favorite video of all time is "Walk Away" by Franz Ferdinand. For some reason, "Portions for Foxes" by Rilo Kiley has stuck with me, as well. (And they're getting back together, I hear. Whoo!)
I know there's some I'm forgetting. I'll probably post more later.
