Oh, i assume most people know what a griefer is, but just in case:
(oh, and if you think Ping and Largo understand each other, they don't. Look at what they are saying, and how they respond. Ping is reacting to Largo's protective tone, not what he's saying.)
largo is looking at the computer case that he just got a static discharge of of the computer case ping and the boys were working on. You know how largo feels about static, what do you think his reaction would be?
Oh, keep in mind that a lot of this is happening very quickly. Electricity travels fast (as does other things). Doing my best to get a proper sense of time across, we'll see if it works.
Actually, this might be clearer after the next comic :)
don't you think that during times when largo shocked some of his, uh, over the top systems, that the results were a little more, uhm, dramatic than just fried chips sitting there?
