Hey Old man, how is your memory doing nowadays? I was thinking if you are still capable enough to remember your birthday or not! Who cares? I remember the day. That should be enough for everybody else in our gang. On this day, I wish you and bless you with all my heart. So Goofy, Have a very Happy Birthday.
It is an honour to be with someone so honest, caring, loving, brilliant, good looking, soft spoken etc, like you. I am privileged to have gained the opportunity to host your birthday party and spend your hard-earned executive salary. It also delights me to even imagine how great I will feel to smash a whole cake on your face. Do not forget the birthday bumps. I literally have been practicing kickboxing for a fortnight for this day. Have a bumpy Birthday dude.
I am the happiest person in the world, this day. It is because that it is your birthday today. You have actually started to go back in ages. No jokes. I am serious. You have looking way younger than what you were in your last birthday. People are not going to believe you that you have turned 70 this year and they are going to bother you a lot by asking you how you managed to stay that way. But please let me know that secret first. I wish you a very happy birthday. Many more returns of the day, Grandpa!
