If you didn't watch the whole thing, you couldn't see why it was funny, though! See, first off, she's giving lap dances in a bar. And she's wearing red cowboy boots. Then, some guy grabs her ass, so she grinds up against him and then punches him out. This starts a bar fight with every man in the bar, and Willie Nelson even makes a brief cameo to smash a beer bottle over someone's head. Pretty soon, all the guys in the bar are down on the ground, so logically, they start to crawl away to make room for the line dancing women. Then, suddenly and sporadically, it cuts to Jessica Simpson washing a car in her bikini, and guess what she's wearing on her feet? Not boots. Just nothing.
That was the most ridiculous concept for a music video... And I laugh every time I see it.
