Staten Island school staffers are drawing laughs on Instagram with a Finish the Lyrics Challenge. An I.S. 61 staffer known as ms.s718 has been making the rounds in hallways and classrooms at the William A. Morris school. Colleagues and a few students finish the lyric, dance, and crack up as the prompt turns into a playful challenge. The videos feature “Sim Simma” and the response, “Who’s got the keys to my Bimmer (BMW)?”. The posts have drawn praise online for the staff’s willingness to participate and the positive atmosphere at the New Brighton school.
