OK, we all know a pop song needs to rhyme but should it not make sense? I give you Amarillo. ....I've been weeping like a willow.... 1. You have shed tears? Willows don't do that. They don't have tear-ducts. 2. You have been behaving like a willow? What! Bending over and trailing your fingers on the ground or in a river? Why would you do that? Bonus willow image for those of an artistic (rather than purely botanical) bent.
