Short and sweet.
I liked it, but not enough that I'd watch it a few more times or so.
However the idea of Jim being this bad ass is quite funny..
As is the idea that this guy just didn't see that coming.
Nice work, but agreed that it is too short. But there's not much else you can put into what is a one line joke. Hard to explain..
Anyway good work. 4/5 8/10
