Actually, joined up letters can be a problem. As an 18-year-old, I worked as a sub-editor on The Beano, and one of my weekly tasks was writing Billy Whizz scripts, including processing the pages when they came in from the artist, Mal Judge. Processing involved adding the speech bubbles and marking out any hand-lettering on the pages that was needed to to assist the action, which was then added in the art department. Being able to draw a bit, I was allowed to put in the simpler hand-lettering myself, rather than bother the busy proper artists with it. On one such occasion, Mal had drawn Billy thumbing through the pages of a book at his customary super-speed. I decided to add to the effect by adding multiple instances of the word 'flick' on either side of the book. Of course, then as now, all lettering is done in capital letters, and as soon as the editor saw the finished page he turned a faint shade of purple and ordered me to change every FLICK to FLIP. There were about twenty of them, and it was all done by hand, so I wasn't best pleased. And when I had the innocent audacity to ask why, the boss demonstrated the problem with great skill, and a tiny FLICK of his biro. Lesson learned the hard way. Though I'm still trying to work out why my Two-Gun Tony script, in which he was pretending to be Clint Eastwood in a spaghetti (bolognaise) western, was rejected the following day, apparently on the same grounds.
But I digress. Is it Mince's day off?
