I’m finally attempting to tidy up all the accumulated detritus in the various rooms I occupy at home and came across this gem in the process.
I fondly remember this daily comic strip by Bill Watterson which appeared in the St. Louis Post-Dispatch after it was first published around 1985. It ceased appearing in 1995, and I assumed it was because Watterson had run out of ideas, but it looks like it’s still being published on-line here: http://www.gocomics.com/calvinandhobbes
That site describes it as: “The beloved comic follows the richly imaginative adventures of 6-year-old Calvin and his trusty tiger, Hobbes.” Hobbes was just a stuffed toy, except whenever Calvin and Hobbes were alone together, when he changed into a real tiger, and not always a dependable friend to Calvin.
Calvin’s dad wants to give his son bicycling lessons, but Calvin would have none of it, claiming in one strip that his dad wants to kill him! Given how his dad fares in the strip shown below, he may have a point.

Just out of interest, what things is dad doing when bicycling that aren’t recommended by knowledgeable on-road cyclists?
