One week is less than 'weeks'

Spring is Here! Which reminds me of Tom Lehrer's comedy song "Poisoning Pigeons in the Park", whose title unfortunately gives away the joke, and I wonder why Lehrer let that get by him. Perhaps the title was imposed on him by his producers, who are notorious for messing up artistic visions in misguided attempts to pander to the popular will. That is, not Lehrer's producers in particular, but producers in general. For all I know Lehrer's producers are or were gems in human form and the title is merely an ironic joke that's too subtle for my poor brain to grasp. My guess would be that that's not the case but I've been wrong before. More than once, even. Like Fred Saberhagen's time-traveling hero, Pilgrim, I can remember three times in the past century that I've been wrong. (Pilgrim is quite a character.) But he doesn't really have much to do with Spring, or with Tom Lehrer, as far as I know, although, again, it could be that the whole story Saberhagen tells is a coded message, understandable to those in the know, explicating Lehrer's song and it's relation to the season, and how it all traces back to trained aardvarks from Ancient Atlantis.
But probably not.
