I have a few problems with this...
I liked the characters for a moment, then realized that Evil Josh's voice is Homer Simpson's voice and then he starts explaining things like Homer also. The ecosystem line is direct from the episode in which Bart leaves a frog in AUSTRALIA and causes the country to dwindle and fall.
I think that it could have been done better with lines that weren't rehashed. I liked the spoon idea, but then it looked as if you just couldn't come up with something to do with it. :-\
