Some Odd Birthday Advice

My great-grandfather used to tell me, "Don't chase after Bananas  because you'll only end up with a book in your head." I never quite understood his advice until one Mardi Gras, I was gardening with my best friend Amy. All of a sudden, we found an underground tunnel! It was happy and spooky sounds came from deep within. Amy saw something interesting inside, jumped in, and I never saw her again. Great-granddaddy was right!
