Very fun and silly.  I liked the ending.  I think in the middle it could be a little more clear with who is speaking each sentence.  For example, The crazy man said, "***".  You could also make separate paragraphs for each line of dialogue.  That would be more clear.

A few notes.  Watch punctuation.  Most sentences should end in a single period.  Elipses (...) are only used in very special circumstances.  For example, if one character has a long pause in his speech.  But 99% of your sentences should not have them.

Make sure you use only one punctuation mark.  !!! and ??? are not standard English.

Good work!.

A man was checking the people who will would go into the fashion show and advertise their clothes.

One time he met the funny Giraffe brothers and one was wearing a giraffe clothes that women wear  and  the other person tied up his neck with the a giraffe scarf  .... The man asked "Where did you come from???" and they answered,  "we came from our home !!! Your so silly!!!".... The man whispered to himself, 'Oh my It should be terrible to talk with them!!!!  They are the craziest person people I have seen!!!!' When he was finished talking to himself, he saw the brothers talking to his doll...One of the brothers said, "Oh my baby,  tell me what you want to tell to me" .... the other brother talked like he was pretending he's a doll. "OK..... I am afraid of that crazy person....."  "Oh ok. We will show our power!!! " and then they poured the tomato juice on the man's head... The man said "help!!!! there's a crazy person who says I'm crazy and they're not crazy!!!"and ran down the hall. The giraffe brothers said askinged themselves, "We were crazy???" ...

And this is the end 

Yes.. you're right: they were  very very stupid fools ......

And they didn't even know they were crazy!!!

And that man made them realize they were fools.
