Harold and Maude, one of my favorite movies.
"You know, at one time, I used to break into pet shops to liberate the canaries. But I decided that was an idea way before its time. Zoos are full, prisons are overflowing...oh my, how the world still dearly loves a cage."
It's brilliant. It's also quite funny in its own way. Oh and the soundtrack is all done by Cat Stevens, absolutely to die for. Watch it next time you have too much homework to do so you watch a movie instead. It's worth watching, promise.
