Joking that a reasonable leaving hour == too early isn't a good joke. It plants the idea that the reasonable hour maybe isn't reasonable in other peoples' minds.
That kind of thing only works as a joke when it's about an obviously late hour (i.e. well past the norms of the company). If someone stays until 9pm to put out some fire and then people joke about working a half day, its obvious that there's no underlying meaning to that, since the leaving hour is well past the established norms
