bilby commented on the word roentgen
"'They're a horde of stupid, dirty layabouts,' said Pettigrew. 'I know them, I grew up among them. You middle-class liberals like to pet them, but I wouldn't even let them breed. What we need is an X-ray device under the turnstiles at the football stadiums. Each man going through gets a blast of 900 roentgens right on the testicles. It would be perfectly painless. They wouldn't know what had happened till they got a wee printed card along with their entrance ticket. 'Dear Sir,' it would say. 'You may now ride your wife in perfect safety.''" - 'Lanark', Alasdair Gray.
