Harold and Kumar go to White Castle. I'd never even heard of it and someone stuck it in the DVD player on a snowboarding trip. Love that movie.
One Flew Over the Cuckoo's Nest Just saw it a couple of years ago and it's probably in my top 10 all-time.
Heavy Metal Parking Lot - Just got around to watching it via Netflix. I remember hearing about it when I was in High School, but never actually saw it, as it was only available as a bootleg VHS. Filmed in the parking lot of a 1986 Judas Priest/Dokken concert, it's the world of Beavis & Butthead brought to life. <object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/WhRCVm-1r2k"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/WhRCVm-1r2k" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>
