"Happy 44th birthday to the king of comedic timing, Simon Helberg! It's hard to believe that Sheldon's other half has reached such a mature age. But let's be real, you'll always be the youngest and most energetic member of The Big Bang Theory squad. May your special day be filled with laughter, love, and a whole lot of nerdy references. Cheers to another year of making us all laugh till our sides hurt. Wishing you all the best on your birthday, Dec 9th."
