For the article, “How much damage can a 6 year-old possibly do? An analysis of the cost of raising a child like Calvin from Calvin and Hobbes,” by Matt J. Michel, which appeared in Volume 1, September 12, 2014, of Proceedings of the Natural Institute of Science-SOFD (Volume 1, Paper 1; first published September 12, 2014, and available online here), reddit user zeinshver pointed out that the estimation of $50 to replace a coffee table into which Calvin had hammered eight nails (click here for comic) lacked an estimation of the cost needed to replace the eight aforementioned nails. The author concedes this point and apologizes for the mistake. On page 2, the first sentence of the “Results and Discussion” section should read, “In total, Calvin caused an estimated $15,955.58 worth of damage...” and not “In total, Calvin caused an estimated $15,955.50” worth of damage....” The author also notes that the entry for “December” in Table 1 should read “672.58” and not “672.50.” In addition, the author notes that Figure 1 should be changed but that the author is too lazy to make a new graph.

These errors do not alter the conclusion of the article that Calvin was a very destructive child.
