“We are armed with the truth. What can harm us if we are armed with the truth?’ ‘Well, a crossbow bolt can, e.g., go right through your eye and out the back of your head,’ said Sergeant Colon.”
― Terry Pratchett, Men at Arms

“There were people who’d steal money from people. Fair

one easy word, would steal the humanity from people. That
was something else.”
― Terry Pratchett, Men at Arms

“Murder was in fact a fairly uncommon event in Ankh-Morpork, but there were a lot of suicides. Walking in the night-time alleyways of The Shades was suicide. Asking for a short in a dwarf bar was suicide. Saying 'Got rocks in your head?' to a troll was suicide. You could commit suicide very easily, if you weren't careful.”
― Terry Pratchett, Men at Arms

“Consider orangutans. In all the worlds graced by their presence, it is suspected that they can talk but choose not to do so in case humans put them to work, possibly in the television industry. In fact they can talk. It’s just that they talk in Orangutan. Humans are only capable of listening in Bewilderment.”
― Terry Pratchett, Men at Arms
