This is my favorite commercial right now. I find myself screaming "Taskute! Kyu kyu Sha!" at random times throughout the day.
This one was made in Iwakuni. I loved Speed Racer as a kid. Plus it cracks me up that he shifts an automatic car.
Often they will take popular concepts and use them. Dustin and I often comment on copyright and trademark infringement.
If that wasn't enough just Search AFN Commericals on YouTube to find loads of homemade fun.
