This episode confused me at first but after watching it a few times. i figured out that enice is not fry's grandpa. my proof: Fry's dad said (in luck of the fryrish) that every man in their family back to minute man yancy fry was named yancy. but his name was enice. and about who was fry's grandpa in the original future: my theory is that enice went gay. then mildredwent off and met yancy.
