Saying Purim Torah, funny (or unfunny) puns based off a misreading of a verse, is an age old tradition in the spirit of Mishenichnas Adar Marbin Besimcha. However, the Gemara in Sanhedrin 99b states:
המגלה פנים בתורה שלא כהלכה אין לו חלק לעולם
He who interprets torah not like the Halacha has no share in the world to come.
Thus I ask, what is the basis for saying over Divrei Torah that are clearly off the mark in its interpretation?
Furthermore, I found that Rav Ovadia Yosef in his Kitzur Shulchan Aruch (Volume 1, 684:17), speaking about the age old practice in yeshivos to appoint a Purim Rav1, excoriates this practice as being a Bizui Talmidei Chachachim - a tremendous disrespect of Torah Scholars.
Is there a blanket license on Purim for these types of practices like we find in the Rema Shulchan Arukh, Orach Chaim 696:8 that men are allowed to wear womens clothing on purim, or unintended damages during the seuda Rema (695:2)?
