Naw, it's just a reference to Saturn. I mean, it's even written right there, "the rings that circle many planets." as in dust rings.
OMG!! I can't believe I forgot about the fluffy Tail thing with Penny. Any other references from MGQ?
Well back in CoC you could run into a burning library with a purple naga trying to cook a potato on a stick while saying "hora hora", which is a direct reference to MGQ's Alice when she accidentally burned down a library to cook a potato.
Oh yeah, there are also LoTR and Doctor Who reference in Bess/Ben interactions (can't find how to put it in spoiler box so I can't go into details here though)
Is the "S/He goes on to detail the sex act called the ‘medusan cascade’" line during Ben/Bess talks a reference to Doctor Who's Medusa Cascade?
