This falls in the category of "other Bear Stories". When I was much younger I was employed in an occupation in the Great Lakes/St. Lawrence Seaway region of N. America that provided a significant amount of time off work, if I was so inclined. During the summer months I took advantage of this option often, electing to bicycle tour in northern Ontario, northern Quebec, and, sometimes, the Maritime Provinces. On this particular occasion, I was touring in the Lac St. Jean, Quebec area in a rural forest near Dolbeau. It was evening and I was getting low on water so decided to stop and filter some from a clear creek so that I'd have enough to see me through the night and next morning. I leaned my bike against some trees along the virtually traffic-free road, crossed over to the other side, and hiked down a steep embankment to the creek to filter. Before doing so, I broke out a brand new large aerosol can of insect repellent (with high Deet content) from my pannier and applied it to my exposed skin. I left the can lying on the rear rack of my bike.
After filtering water sufficient for my needs I climbed up the embankment, only to discover an adult black bear hovering over the rear portion of my bike. I'm not sure what the attraction was but the bear took the large can into it's mouth and, shortly thereafter, I heard the sound of the can depressurizing. A tooth or teeth of the bear had punctured the container and flooded the bruin's mouth with many ounces of insect repellent/Deet. Within a couple or so seconds, the bear made a rather loud groaning noise, quickly pivoted around, and ran headfirst into a fairly large tree. It fell down and disappeared from sight, rolling down the embankment sloping away from that side of the road, in the process snapping smaller saplings and flattening vegetation in its path. I arrived at my bike just in time to see it wobbling into the forest at the bottom of the slope while making coughing-like sounds. I quickly stored away my filter and water containers and hightailed it down the road in case the bear returned and ended up cycling a few extra kilometers before wild camping that night.
