It's an old children's party game, "Parse the parcel", AKA, "Chinese 
Whispers".

Each person hears a whisper, tries to understand it, and then passes it
along as a whisper. At the end of the line, the arrived message is compared
with the original.

Parsers can be many things, but they can be very simple. Here's a list 
parser, which will use the characters in Sep to return a list of tokens 
.... the Lst_t library is left as exercise for student (so as not to do
*ALL* your homework).

 	Lst_t *tokens ;

 	tokens = s_parse( "This is my string", " \t\r" ) ;
 	lst_dump( tokens ) ;

produces ...
    This
    is
    my
    string


Lst_t *s_parse( Str_t Str, Str_t Sep ){
   Str_t  p, q ;
   Lst_t  *x ;

   if( !Str )
     return( (Lst_t *) NULL ) ;

   x = lst_create( 10 ) ;
   p = Str ;
   while( (q = (Str_t) strsep( (Str_t *) &p, Sep )) ){
     if( s_length( q ) )
       lst_add( x, q ) ;
   }
   return x ;
}
