Question:

Is it right to lie for fun if you are only joking?

Answer:

No.  “Neither filthiness, nor foolish talking, nor jesting, which are not convenient” (Ephesians 5:4).  Often the person who is lied to doesn’t think it is funny and this kind of behavior tends to hurt friendships.  Let us try to avoid behaviors that we end up excusing by saying, “Just kidding.”
