I was curious, too, so I looked it up:

excerpt from man wget:
-O file
--output-document=file
The documents will not be written to the appropriate files, but all will 
be concatenated together and written to file.  If file already exists, 
it will be overwritten.  If the file is -, the documents will be written 
to standard output.
