Here's a thing: An editor at Proceedings of the Natural Institute of Science tallied up the total cost of all physical damage done by Calvin and/ or Hobbes over the span of the strip's run.
Say what? I'll let editor Matt J. Michel explain:
The Complete Calvin and Hobbes is a four-volume set containing every published comic strip of Calvin and Hobbes in chronological order. I started with November 18, 1985 (the first comic) and determined every instance in which either Calvin (or Hobbes) caused any type of physical damage or it was mentioned that Calvin had caused some damage. For every event, I recorded the date of the strip and the type of damage caused (i.e., if it was a specific item, or was property damage) with a brief description of the circumstances leading to the damage. There had to be an explicit depiction or mention of physical damage in order for the event to be recorded. Thus, any damage possibly resulting from episodes like “the noodle incident” (or its predecessor, “the salamander incident”) were not counted.
To estimate the cost from damaged goods, I searched amazon.com for comparable items, with some exceptions (e.g., Calvin’s Mom seems somewhat fashionable, so when Calvin placed an incontinent toad on her sweater, I looked for a replacement on jcrew.com). To estimate cost for property damage, I used homewyse.com and fixr.com (using the zip code for Chagrin Falls, OH). In the few instances in which a monetary value was given in the comic, I used that value.
Are there charts, graphs and so forth to further demonstrate his research? You bet. It's science!
This is wonderful. Do yourself a favor and go read it at the almost dirty-sounding PNIS website.
