"Cheese pie, cherry pie."

The story:

It actually was not me. It was the preteen son of my mom's friend. We were sitting in their basement when all of a sudden he started humming quietly under his breath. When I asked "hey Evan, what are you singing?" He said "Oh you know that song 'cheese pie, cherry pie', and sang it with such enthusiasm. I started laughing hysterically and tried telling him it's 'she's my' and not 'cheese pie', but he wouldn't believe me.
