Sega's marketing in the 90's was pretty extreme and didn't make a whole load of sense (Check out some of the Saturn commercials!)
That coupled with some Japanese craziness.. I can see why you don't understand much 

ok this is a little off topic but has anyone seen the two levies stop-motion commercials their really really great here they are

and the other one i think they made a couple others but these are the ones i know.
They should make more claymation commercials nowadays 

I edited your post Mongo so the videos show. The 2nd Levis spot is funny. My sister wore clothes and her hair just like that when we were growing up. The clay is also very un-refined. It's as if they didn't try to smooth things out in the early days, not until the 80's did they really focus on a clean look at most of the studios.

I'm with you Sander, I like the imperfect look better for some reason.
I've seen the Levi commercials before, but never the Sonic one.
I liked the Sonic puppet a lot.
If I learn any other language i think it's gotta be Japanese.
I like to much stuff that is Japanese but I always miss out on the full feel of it because I'm reading subtitles.
