Age hasn't spoiled you. Happy Birthday.
Have fun blowing out all the candles on your cake while you can still count them.
May this year be the best of your life, until the next one. Happy birthday!
Oops, you're old! It's not funny, but you're getting funnier looking!
Nothing could make me more happy than sending this bday message! ...Except, maybe, sending it from the beach in Florida!
Who cares about your birthday. I mean, it's not like a holiday or something…
The letter "B" means only 'Birthday'...
But you can have a few 'B'eers to celebrate!
I don't really have anything witty to say. So Happy Birthday!
No matter how old you get, I don't think you'll ever grow up. Happy birthday!
You're not getting older. You're just a little closer to dying! Happy Bday!
Congratulations on the **th anniversary of your 16th birthday!
You're my best friend. Happy Birthday to you! Just one question - you're paying the bill, aren’t you?
On your special, I thought of giving you the cutest gift ever. But how can I give you yourself??? :)
