What music video can you watch over and over again?

Through his Groov3 hip-hop classes choreographer Benjamin Allen has helped me fulfill some of my wildest dreams: learning the breakdown from Janet Jackson's "If" video, being a Slave 4 Britney Spears and N Syncing my heart out to "Bye Bye Bye."  Both Benji and I have been inspired by music videos over the years, which led to this week's burning question:  What music video can you watch over and over again?  (Fierce dance breaks are appreciated but not required.)  Below are a couple of the videos Benji and I discussed: Madonna's "Human Nature" and Janet Jackson's "If."  Add your faves in the comments section by clicking on the blog headline above.
