It's Always Sunny In Philadelphia is one of the greatest television shows in modern history, and one music teacher is well aware of that!!!
Because he or she had their students sing an AMAZING rendition of the show's classic song Dayman!
We literally jumped out and applauded these perfect performers after they finished, and we're so happy that this video exists!
We hope these youngins stay masters of karate and friendship for everyone!
Check out this FLAWLESS performance (above) !!!
