In December 2015, the cheekily named “Study of Maternal and Child Kissing (SMACK) Work Group” published a study titled “Maternal kisses are not effective in alleviating minor childhood injuries (boo-boos): a randomized, controlled and blinded study” in the Journal of Evaluation in Clinical Practice.

Although the journal is real, the study is (of course) a spoof - a mocking jab at the cool data-driven objectivity of empirical studies taken to an extreme.
