Grandpa always struck me as kind of a shady character. This is from Comic Nuggets by Cedar Van Tassel, who says it’s based on an actual conversation with his Grandpa. The comments at reddit about this point out that 1. shooting at a UPS driver is worse than shooting a drone, b. shooting in a residential neighborhood is illegal, and that 3. drones have cameras, so you’d be caught. They are completely missing the point of the comic, which is that Grandpa is, well, a pretty shady character.
