I recently stumbled across this video while browsing Reddit. Although I take issue with some of the pronunciation (e.g. Deinonychus should be pronounced "die-NON-ih-kus," "not die-no-NICK-us"), this is about as accurate and hilarious a diatribe on dinosaurs as I've ever heard.  For a much longer, maybe slightly less hilarious but equally intense diatribe, ask me why I have serious issues with the movie Jurassic Park as well. Seriously, every dinosaur is somehow misrepresented. Don't get me started.

Anyway, enjoy!
