I am reading a text as follow:
Oh, yes, and Copacabana Beach. Wilbur didn’t like that very much. He got so badly sunburned. Wow, was his face red! It’s the hole in the ozone layer, he figures.
Why in the above text there is "was his face red" instead of "his face was red"? I guess it is a way to emphasis, but I am not sure.
