On the sleeve of Jarvis the pages are numbered, but what one would have expected to be "Page Twelve" is in fact "Page Twelve and a Half". Any ideas why?
How strange! Maybe it's because it's somethng to do with 13 being unlucky, so by calling it 12 and a half, the next page is 12 and a half as well (a picture page) meaning there isn't an unlucky number 13 :P
