Please join me in wishing DrMatrix a very happy 50th birthday.
(Does this mean I can trade him in for two 25 year olds?)
Congratulations, Dr Matrix, have a wonderful day.
Hope you have a wonderful day, DrMatrix. 
C’mon up! Happy birthday DrMatrix.
Happy Bday!
Have a happy, happy day!!
Congratifications, Dr M!! You have now become an Elder Statesman, entitled to pontificate from your store of wisdom!

Happy 5-0, DrMatrix!
I’m just a few months behind you, so watch out.
Woohoo! Boy toys for CajunMan! 
Welcome to the “Half A Century Club” Doctor! 
Herzlichen Glückwunsch!
Quasi
Happy Birthday, DrMatrix!
Ditto for me - I wrap up my first half-century of life in January.
Happy B-day! Is AARP on your speed dial yet?
He’s probably been on their radar for months, FCM!
I bet they’ve already mailed him. I know I received mine the first mail day after New Year’s. Pissed me off somethin’ fierce, lemme tell ya!
But I got over it.
Q
Hey, Happy Birthday!
Send me cake. And chocolates.
Yoopa! It’s all about surviving and looking good doing it. Happy Birthday.
Yay! I get to wish someone here a Happy Birthday who is (slighly) older than me!
Best wishes, Dr.M!
Naughty! Perhaps you should get the spanking today instead of the birthday boy.
Happy birthday, DrMatrix! May all of your wishes come true.
Happy Birthday, Doc. Hope being out there in the heartland is treating you well.
Fifty? Geez, I knew he was old, but I didn’t know he was that old.
Happy birthday. Don’t forget to celebrate (the memory is the first thing to go). Just don’t do anything I wouldn’t do. Well, okay, maybe this once.
I think Cajun Man should be tied up for that remark…
Happy birthday, DrM!
