have a memory like an elephant

But Big Ben had a memory like an elephant.

"That Ella has a memory like an elephant.

Sees everything and seems to have a memory like an elephant and, what is more important, relate one thing to another and deduce a third."

No one anymore has a memory like an elephant, or goes all around Robin Hood's barn, or comes out of it smelling like roses.

Additionally, my 93-year-old father (who has a memory like an elephant) mirrors my view, and confirms that such intelligence has pertained with respect to our family for generations, without truncation.
