For anyone who's yet to discover it, Thog's Masterclass is truly inspiring:

It appears in every edition of Ansible, which is free and highly recommended.
I clicked on Thog's Random Selector and this came up:
Physics Dept. '... no, affinity wasn't quite the right word, it felt more like they were two north poles of a bipolar magnet, each vigorously, automatically repelled by the other.' (Jo Clayton, Blue Magic, 1988) [PM]
• Dept of Anatomy. 'Ace crept back down the corridor, her heart pounding in her neck. She swallowed, trying to push it away, concentrate on what she was doing, but it wouldn't shift.' (Dale Smith, Dr Who – Heritage, 2002) [LC]
• Dept of Genealogy. 'Lord Voldemort – who is the last remaining ancestor of Salazar Slytherin ...' (J.K. Rowling, Harry Potter and the Chamber of Secrets, 1998) [AS]
• Dept of Bunker-Busting Metaphor. 'If the interior of the cone is lined with copper or other metal, this melts and squirts forward with the plasma jet, giving it teeth to punch through armour plate like a fire hose through sand.' (New Scientist, 8 March) [TW]
• Classics Dept. 'We are between the wild thoat of certainty and the mad zitidar of fact – we can escape neither.' (Edgar Rice Burroughs, The Gods of Mars, 1918)
