Was Jesus the First Person to Tweet?

From my room on Toronto, I caught on CBS news this morning Cardinal Ravasi's claim that Jesus was the first person to tweet.  His sermons, the cardinal said, were "brief and full of meaning".
Funnily enough, I talked about this in a segment of my online office hours a couple of years ago, Would Jesus tweet?

Actually, this has given me a great idea for the next NT Pod.
