This is off the subject but some years ago one of the motor companies made a commercial for a small truck. They showed three Sumo wrestlers trying to sit side-by-side in a competitor's truck and not managing to squeeze in. Then the put them in their own truck and they sat in comfort, arms folded.
They were working on the basis that all Japanese look alike to Westerners but I worked for Japanese companies for about 12 years and didn't even have to look hard to see they weren't the same three wrestlers.
