I giggled at this passage that I just encountered in The Joe Orton Diaries:
Peter Willes rang up. ‘What do you mean by sending me such an atrocious script?’ he said. ‘What?’ I said. ‘All the “O’s” are out of line. I can’t read a script like that. Haven’t you another copy? ‘No,’ I said. “I’ll have to get it retyped,’ he said. ‘I can’t let the actors see a script in that state.’ ‘Did you read the script?’ I said. “A little.’ ‘What did you think of it?’ ‘I thought it rather dated,’ he said, ‘though that may have been the effect of the “O’s”.’
See? Good typography makes a difference.
