The 'Friendly Rivalry' Roasts


For the friend you've competed with, laughed with, and always secretly admired. These messages are all about good-natured ribbing and one-upmanship.
1. Happy Birthday! Remember when we used to argue about who had the bigger muscles? Now we can argue about who has the better hearing aid.
2. Congratulations on another year, my friend. I was going to get you a subscription to AARP, but I assumed you were already their president.
3. Happy 78th! You've officially reached the age where your back goes out more than you do. Don't worry, I'm right behind you... as usual.
4. Another trip around the sun! You're still hitting hard, but let's be honest, now it's just your afternoon nap that hits hard. All the best!
5. To my favorite sparring partner: You've always been a little ahead of me in age. Thanks for testing out the "golden years" for me. Let me know what to expect! Happy Birthday!
6. Happy Birthday, Sly! I'd say you're getting old, but that would mean I am too, and that’s impossible. So, you're just getting… more classic.
7. I hear 78 is the new 50. Of course, the person who told me that was also trying to sell me a ridiculously expensive sports car. Sound familiar? Have a fantastic day!
8. Happy Birthday! Don't worry about the candles, I've already called the fire department. It’s the least I could do for my oldest rival.
9. You may have drawn first blood, but I’m pretty sure I’m winning on hair. Happy Birthday, you magnificent beast!
10. Congrats on 78! You’ve still got it. Of course, “it” is now a tendency to groan when you stand up, but you own it well.
