Keep it kind. Avoid jokes that could embarrass him in a family group.
Add a photo. A funny old picture with a caption gets the best reactions.

Strong family ties matter. According to UC Berkeley’s Greater Good Science Center, saying thank you builds closer relationships, so a grateful birthday message can strengthen your bond with your brother-in-law.
