Dear Brother-in-Law,

I know what you’re thinking, “Jerry Seinfeld writing a thank you letter in a formal style? What’s the deal with that?” But let me tell you something, my good sir, expressing gratitude is always in style.

So, I just wanted to take a moment to thank you for being the Kramer to my Jerry, the Newman to my mailman, the George to my Jerry (although let’s hope our relationship is better than theirs!).

Your presence in our family has been like a soup that just keeps getting better with every spoonful. You add your own unique blend of spices and ingredients that make the soup that much more enjoyable to savor. Like a good soup, you bring warmth and comfort to our lives, and we are so grateful for that.

Thank You Letter For Brother In Law Sample 2

Dear Brother-in-Law,

I wanted to take a moment to thank you for all that you do. You are truly one of the most hilarious people I know, and I mean that in the best way possible. Your jokes may be corny and your puns may be eye-roll inducing, but I wouldn’t trade them for anything.

You bring so much joy to our family gatherings, even if your “dad jokes” do make us groan. But let’s be honest, we secretly love them. I mean, who else would make up a song about Brussels sprouts to the tune of “Bohemian Rhapsody”?

Your outrageous sense of humor never fails to put a smile on my face, even on the darkest of days. And even though you insist on wearing those Hawaiian shirts to every occasion, somehow you manage to make them work. I mean, you’re practically part of the luau!

So as much as I tease you about your silly jokes and tacky attire, I truly am grateful for you. You make every family gathering more fun and I can’t wait to see what ridiculous antics you come up with next.

Thank you, Brother-in-Law, for being the comedic genius that you are.


Your Adoring Sister/Brother-in-Law
