Father-and-son Halloween costumes are a fun way to bond on this spookiest of holidays, but this past Halloween, one father-son duo came up with a mind-bending costume that will leave you scratching your head. They dressed up as each other, using each others’ clothes and makeup to leave you wondering which is which.

What makes the image, which was posted on imgur by jschu2711, even more confusing is that the “after” image is on the left, so it takes a moment before you realize what each of them are actually supposed to look like!
