the pancake race
The pancake race, with the women frying along, throwing and trying to catch their pancakes, provides a great deal of enjoyment and is frequently shown on television in 1950, a similar pancake race was organized in Kansas, USA, and has continued ever since. It takes place on the same day, at exactly the same time. Times are clocked in both sides of the Atlantic and there is a close competition to see whether the British women or American housewives run faster.

panasonic和national都是松下品牌不错，区别在于panasonic是松下娱乐数码产品的品牌，national是松下白色家电的品牌（就是厨房、卫浴和照明等），
不过在2003年松下将旗下的两个品牌统一为panasonic，现在松下的品牌是panasonic。

National，是松下原来的商标；Panasonic是松下吞并了几个小公司以后整合的商标。
national是指松下的子品牌松下电工，以工业电气类产品为主
panasonic是以电器类民用家电电器为主，也属于子品牌
只是松下公司的两个品牌而已.
就像丰田公司里有丰田和凌志一样
