I love this if only because the final punchline was so good. I admit it was a little predictable, but it was still lots of fun. I know you have made more stuff with these characters. I guess you just didn't call them "Smugheads". The voices are nice. I like how you introduce these characters.
I admit that this joke isn't very funny. The buildup is much better. I just thought this was laid out well. The animation is as slick as ever. I always want new stuff like this.
