I'm not sure you know what Tourette's is.
But I'm sure plenty of other people will be getting on your case about that, so I'll let them do the work.
The concept was mildly amusing: A T-rex with anger management problems who can't do anything because his arms are just tiny stumps. However, there's not much payoff to it, as all the jokes are rather predictable and kind of just blend together after a while. The only joke you seemed to be milking was the way the T-rex roared at ear-shattering levels every time he got mad, which really gets old after a while. And then there's the ending. Not only did it make no sense, but it used a shitting joke for no apparent reason. All said, it really misses the mark.
