"Well, slap me with a moldy turnip and color me flabbergasted!" source: International Data Group's Computerworld Thread topic? Hmmm....how about this: In your version of English, would the flabbergasted statement above be immediately obvious? Is the meaning clear to you? I'd never come across this particular collection of mixed metaphors, but found it strong and clear, in a muddled sort of way. Would people in your neighborhood understand it to mean, "I'm absolutely amazed"? Hint for BE speakers: you might substitute 'swede' for turnip if that feels more idiomatic.
