Dr. Pepper, please do not do that. it really is not funny.
Re the hilarity of school pranks: Some of them are not so funny. My husband was teaching in a “Choshuvah Yeshivah” in a class filled with obnoxious fifth graders. The nicer he was to them, the more chutzpahdig they became. This was especially unfortunate as he is a Baal Teshuvah with the idealistic notion that unzereh students are tzadikimm because they grow up in Torah-filled homes with derech eretz. He was sadly disillusioned both in this yeshivah and elsewhere. But I digress…
The boys thought it would be a real hoot to remove the pins from the hinges of the closet door where class supplies were kept. They reasoned that the next time my husband opened the door, the door would fall on him. HAHAHAHA!!! What a laugh riot that would be! Unfortunately, they did not count on the PRINCIPAL coming into the classroom, and for some reason HE needed to open that closet, so you can guess what happened. My husband was flabbergasted and very embarrassed, and the principal, who fortunately was not hurt, just very startled, became enraged. Although it is clear it was the fault of those students who did this, it reflected badly on my husband, as well. It really upset him that frum kids should do something so mean-spirited and think it to be a joke. Plus they were LUCKY no one was injured. it could have just as easily gon the other way, and it could have happened to him.
I don’t like practical jokes that potentially can cause harm to someone or embarrassment, which is a major aveira.
