I'm not sure what's worse, the fact that McDonald's Japan's strategy team could only come up with "lets sell hotdogs!" or that their marketing team thought "McHotDog Classic" was actually a great name. I guess they just wanted to further the stereotype that Japan is a WTF rich country.

マックホットドッグ クラシック

I'll try to capture the commercial if I see it on TV again but it basically shows business men and women walking on the street and one by one they start to act out as if they're playing baseball.
