兒子的數理統計教科書上有一道關於癩蛤蟆求愛的作業題

Male toads often have trouble distinguishing other male toads from female toads, a state of affairs

That can lead to awkward moments during mating season. When male toads A inadvertently makes inappropriate romantic overtures to male toad B, the latter emits a short call known as a chirp. Below are the lengths of the release chirps measured for 15 male toads innocently caught up

in misadventure of the heart. (數據略)

看來癩蛤蟆在求愛方面確實笨, 連公母都分不清.不過癩蛤蟆畢竟也有romantic overtures.

人求愛時不會分不清男女. 但弄清對方的態度經常也是一道難題. 誰也不願意丟面子.

不會有鄧貴大式的癩蛤蟆.
