Silent "h"

Student: (before answering a question): Ummmmm…

Spanish teacher: Remember, anyone who says the word “um” before he or she answers a question has to give a penny to the “La bolsa de Um.” Pay up.

Student: No, no! I said “Hum!”

Spanish teacher: No, you said “Um.”

Student: I’m serious! I said “Hum!” because in Spanish you don’t pronounce the “H” sound.
