There were lots of things that he could have gone for, and the one thing that he did take home may surprise some fans.
For Helberg, the wardrobe was something meaningful, even though wearing these clothes grew tiresome. He chose a rather inconspicuous item, as most people are inclined to gloss over a belt buckle when taking his entire wardrobe into consideration. It may seem like an odd choice, but Helberg had his reasons.
He would say, "I took the Nintendo controller belt buckle that I wore in the pilot. It's small and indestructible and it means something to me. The character came together fully when I put on that crazy wardrobe that [Big Bang costume guru] Mary Quigley designed so brilliantly."
