Grip, dude!
It is hard to judge something that is so short, but I will try as hard as I can. It is interesting to feel connected with these characters again and see what they are up to. I believe that they are based on yourselves, or something like that. I just think that "Rat" is one of the worst names you could give a person. Although, I suppose a name like "Swiffer WetJet" isn't much better. Anyway, I did not think that this punchline worked as well as it did in your first short, but it was still pretty fun to watch.
