Except it seems the prank/protest backfired when photos of the signs were taken seriously, and posted on a few popular Twitter accounts without a hint of satire.

The Twitter hashtag #NationalBumSmackingDay soon began trending worldwide, though it's unclear if anyone actually went around smacking random strangers' behinds.

But, as one astute Twitter user pointed out, those who celebrate #NationalBumSmackingDay today will be celebrating #ImNotAtWorkBecause IGotDoneForSexualHarassmentDay tomorrow.
