T-Rex an herbivore?

A lone Triceratops wanders through the forests of the late Cretaceous, grazing for shrubbery. He looks up as a sudden shake of massive footsteps echoes through the woods. It is a Tyrannosaurus Rex, lumbering towards Triceratops. But then, Rex stops at a tall tree full of large, flat leaves. He closes his massive jaws around one branch and slides his head down it, his teeth catching leaves to eat. The Triceratops turns his back and continues grazing, unthreatened, as the Rex gorges itself on its leafy snack. NO. Just, no. How did that segment strike everybody? An aquaintance of mine read an article that states that, because of T-Rex's "weak teeth, useless arms, and ill-proportioned, stubby legs," it was a herbivore. Furthermore, the article stated that most, if not all specimins of T-Rex found have had green on their teeth. This article had my aquaintance convinced that T-Rex was in fact an herbivore. Can you believe this???!!! Obviously, I don't buy any of this, and I wanted to open up this thread to see just what kind of reactions this article brings about. Please, everyone, Team Rex or not, defend the Tyrant King from this blasphemy!
