Funny Birthday Messages to Celebrate Your Grandson

“Happy Birthday, superstar! 🌟🎉 Remember, you’re not getting older; you’re just increasing in value like a rare collectible. Except, in your case, you’re more like a comic book—slightly crumpled, but worth a fortune in laughs! May your day be filled with more fun than a barrel of monkeys (and fewer chores than an actual barrel).” 😆🦸‍♂️
