May you live as long as you want to, and want to as long as you live.
May you live to be old and toothless.
Smile while you've still got the teeth, Happy birthday.
So many birthdays. So few candles. Next year, may your birthday wish be a bigger cake.
Forget your past, it's already done. Forget your present, too; because I forgot.
You're not getting older. You're just a little closer to dying!
