Most of you by now have seen at least one or two of these photos, where SM employees rearrange the lobby chairs inside the SM building to relay a special message for artists on their birthdays! 

The employees not only put in all that effort to rearrange the chairs, but they get creative according to the limited number of chairs they have! For members of EXO, you can spot different, unique messages, including "BH. B-DAY" for Baekhyun, "Suho DAY!" for Suho, and "REAL. PCY" for Chanyeol! 

What happens when there are multiple birthdays? Well, in one photo below, the employees have arranged the chairs to say "210 S.S.S.", to represent the February 10 birthdays of Super Junior's Siwon, Girls' Generation's Sooyoung, and Red Velvet's Seulgi! 

How much fun do you think the employees will have for the next SMTOWN artist celebrating a birthday?
