Interestingly the 'lay/lie' issue is addressed by Geoffrey Pullum today in Language Log and he sticks to the (in)transitive distinction more than Merriam-Webster does. I think there may be a bit of transatlantic variation here on the levels of acceptability. I also wouldn't rhyme 'mum' and 'from' any more than 'mom' and 'crumb', though I wouldn't call someone out on it.
This is all just the result of a typing error. I'm sure that cfm simply omitted to type the word "Brum" at the end of his line in his line before posting.
The Pru [he's a bit of a cad].Now stop being a silly, Rosie. You're worth more than this pettyfogging quibblesome nonsense. And I do believe that's the very first time I have used the word pettyfogging - - - :^)
