An English teacher told his students that when pronouncing a word beginning with the letter "H" they should ignore the "H" as in hour, honor, and honest. That day when leaving for class, he left a note for his assistant, "Please heat my rice for me." When the teacher returned to his office, he met an empty bowl. He asked the assistant, "Where is my food?" The assistant replied, "You said I should heat the rice for you, but you also instructed us to ignored the 'H.'"
