Guillemots lay a single egg. It's pear shape stops it from rolling off.

海鸠只产一枚蛋。梨形的蛋不易滚下悬崖。

My hedgehog is small enough to be a pear shaped handful of quills with a fuzzy belly, but he's squirmy enough that I use two hands.

我的刺猬小到只有一把梨形的羽毛笔，肚子上毛茸茸的，但他很灵活，我可以用两只手。

Like, if you are somebody who has a pear shape, you already know this tip doesn't work, you know, because it's probably never worked for you.

就像，如果你是一个梨形的人，你已经知道这个技巧不起作用，你知道，因为它可能从来没有对你有用。
