Another year older, wiser, and still as charming as ever! Happy birthday, bro!

Another year, another reason to thank our parents for not selling you when they had the chance. Happy birthday!

Another year, another reason to remind you that you're still not the favorite child. But hey, at least you're the funniest! Happy birthday!

Age is merely the number of years the world has been enjoying you. Keep spreading the joy, bro!

Happy birthday! Remember, you're not getting older; you're getting closer to looking like Mom and Dad!

Happy birthday to the one who's been my partner in crime, my co-conspirator, and my partner in annoying the rest of the family!
