Folly of the Faithful Canine

To those who haven’t read it, here’s a detail not well known:
In Mary Shelley’s Frankenstein, old Victor worked alone.
He had no lab assistant till the first recorded play,
Presumption, which I doubt is still performed a lot today.
The bumbling servant there was Fritz, who later would appear
Within the film of ’31. To add to viewers’ fear,
He had advanced kyphosis like the dude at Notre Dame.
Dwight Frye, who also worked that year as Renfield (he’s the bomb),
Became a different henchman in the sequel with the bride.
The next two films, however, let Lugosi come in stride
As Ygor, whose deformity resulted when the town
Had hanged him but messed up at it (why was he still around?).
This Ygor was a blacksmith, not a toady in the least.
Indeed, he took control of the reanimated beast.
The later House of Frankenstein had Daniel take the form,
So Universal Studios made hunchbacked aides the norm.
The first assistant Igor, tho, was Warner Bros.’ doing
In House of Wax, a Frankenstein-free film for 3D viewing.
It wasn’t till Young Frankenstein that hunchback Igor came,
And he pronounced it “eye-gore,” so it wasn’t quite the same
As that which has been used in countless parodies to date.
Who knew that a composite’s role in lore could be so great?
