I was standing in line at Chik-fil-A, waiting to get my sister's sweet tea refilled, not knowing that all you had to do was go over to where the orders are laid out and ask there. We don't go to Chik-fil-A that often, so it's not something I considered.
In line in front of me is a heavyset man with a cap on, and his wife. He was wearing a "Bazinga!" t-shirt with a picture of Sheldon above it. I was wearing a t-shirt that had the Klingon version of "Revenge is a dish best served cold," along with the English translation underneath, and Sheldon between both.
The wife noticed my shirt and said, "Hey, look at that!", and her husband and I talked briefly about our love for The Big Bang Theory. Then his wife told me, "They call him Sheldon at work." I then listened to them deciding what to order, and when he told his wife what he wanted, he sounded exactly like Sheldon sounds when he orders something.
I thought, "Only at work?"
