Hello, friends. I've just watched a film -The curse of the Jade Scorpion, Woody Allen- in wich they used this expression: My Gosh! Who'd thunk it! I looked up the word thunk and I found out that it's the past and participle of think. The Merriam-Webster Online said that it was dialect. So, I'd like to know what kind of dialect it is, from where and any other information you could give. I think I heard Goshbefore, but is thunk common nowadays. Thank you, Mr Bones. And please, correct my mistakes.
