Riff reference to Lolita?

[talulah gosh]

Around 40:00, the line "Her name is Dolores Sumuru". Is this a nod to the guy's creepy demeanor via Nabokov (or West World if you're a youngin)? He definitely gives off James Mason as Humbert Humbert vibes.
I know it's a tiny riff amongst many, but I love finding a reference to Nabokov in Rifftrax.
