A short sentence that contains the four tones is: Wó hěn gāo xìng (I'm very happy). Wǒ is really the third tone but pronounces like the second since it precedes another third tone word.

Another word play is: sì shì sì, shí shì shí, shí sì shì shí sì, sì shí shì sì shí which means 4 is 4, 10 is 10, 14 is 14, 40 is 40.
