So imagine my surprise to come across a How To Write book in the library recently that seriously suggested 100 alternatives to 'said', including the e word. Most of them were simply wrong. Take 'Woody Allen is so funny,' she laughed. Okay, now say it aloud, at the same time as laughing. Try it. Then try snorting your words, or giggling them. It can't be done. You can laugh, or snort, or giggle, and then speak, but not both actions at the same time.
I'm all for adding colour to writing, but in the case of speech the only variations that work are about volume: 'Be quiet,' he whispered, or 'Stop that now,' she shouted. In general, plain old said is safest. It's a word that disappears, like 'and' or 'the'. If you feel you've got too many 'saids' floating around in your writing then either look for ways to hide them (eg within speeches), or cut them completely (substituting actions if necessary). 'But don't be tempted to use highly coloured alternatives for said,' she ejaculated. Unless you want us to snigger.
