I wonder how well this has aged. It was 50 years old the first time I saw it, so maybe it is truly timeless. On the other hand, there is a lot of low-hanging fruit; has it gotten corny (to mix my metaphors into a tasty, tasty medley)?
You can really only shoot an elephant in your pajamas once; just like in music, you can really only Rock once around the Clock, or have one only Calendar Girl. I guess you can also have a Mayan Calendar Girl, but not after 2012.
It might be low-hanging, but they got there first, and picked the hell out of it.
