“It makes sense if you don’t think about it.”
This folk phrase was said by a friend during class. This example is somewhat different from the others because the performer did not know it was folklore. He noted:
“I legitimately thought I made it up.”
“I mean, like, it’s probably from somewhere else, but just like subliminally messaged.”
Here is another example of this phrase, used ast the title of an article: http://www.rweconomics.com/It_makes_Sense_If_You_Don’t_Think_About_It.htm
It is somewhat of a parody of a different common phrase: it makes sense if you think about it. This variation refers to things that only make sense in general terms, and stop making sense under scrutiny.
