These Chick-fil-A employees weren't about to let a language barrier get in the way of wishing their coworker a happy birthday.

The staff of a Lawton, Oklahoma Chick-fil-A secretly learned how to sing "Happy Birthday" in sign language for their hearing-impaired coworker named James.

When James rounded the corner, however, he was surprised by the entire staff "singing" happy birthday.

"We had the best time learning to sign the ‘Happy Birthday' song for our fellow team member who suffers from hearing loss," one of the workers said in a Facebook post. "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!"
