I don't have enough information to know who Gordy specifically is in this story. He could be an ordinary person, a family member, or someone with a unique role within the context of his home.
I'm not sure specifically which 'Secret Rhonda Story' you are referring to. There could be many stories with that name. It might be a personal story within a family, a fictional story created by someone, or something specific to a certain community.
Yes, Gordy the Chimp is a real story. It was inspired by actual happenings and might have been embellished a bit to make it more engaging and captivating for the audience.
