Just the facts, re: "Is it really a haiku?" Well, it's actually a joke, and therefore exempt from strict rules of ... haikuity, I guess. You have to imagine Jack Webb's voice as Sgt. Friday as he speaks in that deadpan cop's voice: "Eleven fifty-seven PM..." -- it begins like a description of a stake out or something, but then it ends with an enigmatic reference to a flower, inducing a chuckle.
