I forget where I first read it, but some commentator has a rule of thumb about newspaper/magazine stories and comedy, which states, roughly: “Any time a piece tries to give an example of something that is supposedly humorous, the example will never be funny.” I think “Cruelty to small animals is one of little Bobby’s few outlets,” (which I can’t even place in an episode) is a pristine example of that rule.
Thanks to Robert for the heads up.
