There was this Asian lady married to an English gentleman and they lived in London. The poor lady was not very proficient in English, but managed to communicate with her husband. The real problem arose whenever she had to shop for groceries.
One day, she went to the butcher and wanted to buy pork legs. She didn't know how to put forward her request, and in esperation, lifted up her skirt to show her thighs. The butcher got the message and the lady went home with pork legs.

What were you thinking? Hellooo, her husband speaks English!!

Later he said, "Under some conditions, however, it may be possible for an electron to combine much more closely with the H nucleus, forming a kind of neutral doublet. Such an atom would have very novel properties. Its external field would be practically zero, except very close to the nucleus..." In 1932, Chadwick discovered the neutron.«
