Just to throw in a bit of culture, there is a nice word play with the word often in the "Pirates of Penzance" by Gilbert & Sullivan.
GENERAL: Tell me, have you ever known what it is to be an
orphan?
PIRATES: (disgusted) Oh, dash it all!
KING: Here we are again!
GENERAL: I ask you, have you ever known what it is to be an
orphan?
KING: Often!
GENERAL: Yes, orphan. Have you ever known what it is to be one?
KING: I say, often.
ALL: (disgusted) Often, often, often. (Turning away)
GENERAL: I don't think we quite understand one another. I ask you, have you ever known what it is to be an orphan,
and you say "orphan". As I understand you, you are
merely repeating the word "orphan" to show that you
understand me.
KING: I didn't repeat the word often.
GENERAL: Pardon me, you did indeed.
KING: I only repeated it once.
GENERAL: True, but you repeated it.
KING: But not often.
GENERAL: Stop! I think I see where we are getting confused.
When you said "orphan", did you mean "orphan",a person
who has lost his parents, or "often", frequently?
KING: Ah! I beg pardon-- I see what you mean -- frequently.
GENERAL: Ah! you said "often", frequently.
KING: No, only once.
GENERAL: (irritated) Exactly-- you said "often", frequently,
only once.
