If you haven't seen "Not That Chris" by Chris Pine, you really should. It's set to the tune of Uptown Girl, but it's about how Chris is...not that other Hollywood Chris. 11/10 song, would recommend.
Holy hell, that's what that song is called? It's one of the songs I grew up with; it's pretty fun. I wouldn't call it the greatest song of all time, though; I'd say it faces stiff competition from, at minimum, Livin' on a Prayer (Bon Jovi) and Take on Me (a-ha). At least, I prefer those to this one, but I still like Uptown Girl all the same.
