I think the disclaimer we have for Purim Torah is excellent, in size, position, and content. I would like to suggest a small change:
Instead of "This question is Purim Torah and is not intended to be taken completely seriously. See the Purim Torah policy."
What about "This question is Purim Torah and is not intended to be taken seriously. See the Purim Torah policy."
I just don't see what "completely" comes to add. Almost all PTIJ questions are not meant to be taken seriously at all, and in fact, serious answers may be off-topic.
