Use the number returned by random() as the index to an array of phrases.

Something like

char * phrases[] = {"Phrase 1", "Phrase 2", "Phrase 3", "Phrase 4"};

void setup()
{
  Serial.begin(115200);
  randomSeed(analogRead(A0)); //attempt to make the sequence more random
}

void loop()
{
  byte index = random(0, 3);  //get a number between 0 and 3
  Serial.println(phrases[index]); //use it as the index to the array of phrases
  delay(1000);
}
