讀詩篇同讀屎片有乜分別?

讀詩篇同讀屎片有乜分別?讀完詩篇無病呻吟痴夾癲.
讀完屎片做到貪曾和亞扁.

讀詩篇：難懂難讀；讀屎片：仔仔女女賴尿屎，換尿屎片手舞足道…好好玩！

冇分別,

讀完之後, 一樣搵唔到食。

屎片 is not any kind of information but just an expression of useless general item.
詩篇 is part of a paragraph in Holy bible in Christianity.
讀 means read or learn.

So the former of 讀詩篇 means reading or learning part of a Holy Bilble and the later of 讀屎片 means reading some useless information. There is no 屎片 in the school curriculum but there is bible class in some of the school with Christian background.
