Thread: using indexof to remove first two words of string

my code words but its ugly;

Code:

string word = "Hello World donkey kong";
            if (word.Length > 0)
            {
                int i = word.IndexOf(" ") + 1;
                string str = word.Substring(i);
                int j = str.IndexOf(" ") + 1;
                string str_2 = str.Substring(j);
                Console.WriteLine(str_2);
            }

it prints "donkey kong" to the console screen which is what i want. can you show me the correct way to do this with cleaner code because this is really hairy right now.
