I find the lyrics baffling.

And why a bush of rue? The site ediblewildplants.com has this to say:


"In large quantities all parts of this plant (rue) are not safe to take. Rue should not be used at all by pregnant women as it can induce abortions. The sap contains furanocoumarins which sensitize the skin to light and can cause blisters or dermatitis in sensitive people."

Not to mention that if you look at images of rue, it is hard to imagine an adult fitting under a bush of it.
