Employees of a Lawton, Oklahoma Chick-Fil-A gave the greatest surprise to a hearing impaired coworker when they all learned "Happy Birthday" in sign language.

James entered the kitchen to a slew of his coworkers signing the song, while he smiled happily and watched.  

They wrote on the post:

"We had the best time learning to sign the 'Happy Birthday' song for our fellow team member who suffers from hearing loss. We love you, James, and we are so thankful that you are a part of our team! We look forward to celebrating many more birthdays with you!"
