I was reading 'Improve Your Grammar (Collins)' today, and I couldn't help but laugh when I read the following passage that demonstrates the importance of punctuation: "A well-known illustration recounts the fate of a warrior in ancient Greece who, on the eve of leaving for a war, consulted the Oracle at Delphi. Thou shalt go thou shalt return never by war shalt thou perish, he was told. The overworked Oracle spoke without pause, so the warrior naturally assumed that he meant Thou shalt go, thou shalt return, never by war shalt thou perish and departed with great confidence. Unfortunately he was killed in the first battle, never realising that what the Oracle really meant was, Thou shalt go, thou shalt return never, by war shalt thou perish." P.S. Punctuation is the difference between “I helped my Uncle Jack off a horse” and “I helped my Uncle jack off a horse”.
