I was going to mathematically relate your age to today’s temperature (outside) with a very simple equation, but I decided not to. >.>; Happy birthday (nonetheless)!
Edit: Without windchill, of course. 
With or without windchill?
Happy birthday, Sin.
TICK-TOCK
Happy birthday.
Happy birthday, Sin! I wish you success in work and happiness in your <strike>sex life</strike> personal life.
f(x) = SinsAge(Temperature outside)
Where SinsAge(x) turns x into Sin’s age 
Happy birthday!
Happy birthday. Good luck with your project.
Given that outside is cold enough to kill a puppy…
Happy birthday Sin!
Happy birthday, Sin! Hope you get caik!
I don’t think we could mathematically extrapolate squat from the current temperature out where I am (unless we use Celsius and avoid using division since you’d be working with -17 & 7/9ths degrees)
Still though, Congrats & Happy Birthday to you too Sin! :toast:
Use Kelvin. 
Either way, grats Sin!
At least Sin’s long hair should help him stay warm.
Happy Birthday, btw. Have some Scientifical Caik.
Yay happy birthday
Thanks everyone! And I hope its without windchill :O! I’m not THAT old! God damn its cold this week. Holy shit.
Happy birthday! Oh wait I’m too late…
Happy birthday! (and NO, you’re not THAT old, give it a few more years :D)
Happy (slightly late <<) birthday, Sin. 
Happy Birthday, Sin!
(And yes, it’s cold all over the place. Damn weather patterns.)
Happy Birthday Mr. Sciency Man!
Edit: Dr. Sciency Man!
Happy Brr…day!
There are no happy birthdays. Only cakes that haven’t been eaten.
