The San Wui Commercial Society Secondary School board clarified that Principal Lee Cheuk-hing was merely conducting a live workshop on "Advanced Verbal Abuse" during the school’s Singapore tour.

Students noted that while the technology seminars were mind-numbingly dull, watching their leader screech Cantonese profanities at a security guard provided more educational value than any textbook.

"He really showed us that a high-paying job doesn't stop you from acting like a rabid street dog," remarked one inspired teenager.

The principal’s decision to make taunting faces at the Safra guards was reportedly part of a new curriculum module on "How To Lose Everything In Thirty Seconds."

The board suspended Lee so he can focus on his true calling as a full-time professional YouTube comment section.

Local security guards have requested a bonus for surviving a Cantonese soap opera without the benefit of subtitles or a stunt double.

The students have since updated their resumes to include "Witnessing A Mid-Life Crisis" as a core competency.
