A polite and sophisticated rejection I'd like some nice witty phrases to say no in other words. "When pigs fly" is little bit inappropriate. Give me some ideas, please

The use of the verb "remind" : with the preposition "of" and without. I noticed this verb unfollowed by the preposition of. Therefore "remind" can be a direct verb up to the context. When I mean the resemblance I use it as a direct verb: your smile remindes me the smile of the person whom I want to marry someday. When I mean just a memory I use this verb followed by the preposition of: you don t need to remind me of the matter, I ll solve it ASAP. But I heard anather sentense: you remind me of a star (super star, a model). Is this correct too?
