Reality Bites was one of the most iconic movies of the 90s. How could it not be with that cast? Winona Ryder, Ethan Hawke, Ben Stiller, Janeane Garofalo, Steve Zahn, Renee Zellweger... It was destined for awesomeness.
I couldn't find a decent video of Ethan Hawke actually singing I'm Nuthin'. You should really just go watch the movie anyway. It's totally worth it.
