on page 63. It corroborates what is said here. At the time, he thought
there would be 4-5 grooks, not the ~7,000 that he later wrote.}} He became an underground passive resister. He found a way to encourage resistance
through the use of poems, which he called "gruks" ("grooks" in English),
and began publishing them in the daily newspaper "''[[Politiken]]''" under the pseudonym
"Kumbel Kumbell"{{refn| "Here is the reason why: Piet is the Dutch form of the name Peter or Petrus, which means rock, stone, and Hein is a way of spelling 'hen', the old Danish word for a whetstone. 'Kumbel', or 'kumbl' as it strictly speaking should be written, also means stone, though more a grave monument. In other words, Piet Hein, or Stone Stone can, in a way, be translated by Kumbel Kumbel. He originally wrote the second word with two Ls, also later the signature became just Kumbel – the name he is at least as well known by as his own."<ref>[http://www.piethein.com/usr/piethein/HomepagUK.nsf/webdocs/2e8962af9e1fffeac1256c860039c7eb?OpenDocument&ExpandSection=1 piethein.com] {{webarchive|url=https://web.archive.org/web/20100804202919/http://www.piethein.com/usr/piethein/HomepagUK.nsf/webdocs/2e8962af9e1fffeac1256c860039c7eb?OpenDocument&ExpandSection=1 |date=4 August 2010 }}</ref>}}.
