7. Clerks II (2006)
http://www.youtube.com/watch?v=tXJu2YoQ-aw Over a decade after his indie hit was released, divisive director Kevin Smith made the sequel Clerks 2. We again see Randall and Dante at crappy dead-end jobs, with Dante on the verge of marriage and leaving town. Atop the roof of the fast food restaurant, Rosario Dawson helps Dante learn how to dance for his upcoming nuptials. As the Jackson 5 track ABC plays, the two begin to dance on the roof. The song infects the rest of the restaurant, breaking into a show-stopping dance number involving dances in the parking lot and a dude in the bathroom we really didn't need to see more of.
