Here is a mashup video from a scene from the Gumball episode "Halloween" with that from fan artist Mike Inel, using both the original English and Japanese dubbed audio.
EDIT (03/03/15): As of this writing, this video reached a milestone of having over 1 million views.
I'm not PewDiePie or some other internet celebrity, but I'm deeply humbled and grateful that this video has reached this many views from around the world. I thank you the viewers for your support and I also thank Mike Inel for his artwork. Credits also to Cartoon Network for the Gumball clips, Cartoon Network Japan for the dubbing, and last but not least, Japanese voice actress Junko Takeuchi (the voice of Naruto) as Gumball. You guys rock, seriously.
