In I Love Me, Vol. I, Mike Bonner recognizes a handful of palindromes involving Eva and a cave, including "Eva, can I pose as Aesop in a cave" and "Eva, can I stab bats in a cave?," both attributed to Leigh Mercer, and "Eva can, I see, bone no bees in a cave," by J.A. Lindon. However, there's lots more that can be said about our troglodytic Eva.
