I've had a Cthulhu/South Park Mash-up in my head all morning... not only the theme tune but little Mythos-related South Park characters...

Help meeee!!!!! :p

I'm goin' down to Dunwich gonna have myself a time,
Friendly faces everwhere humble folks without temptation,
I'm goin' down to Dunwich gonna leave my woes behind,
Ample Parking Day or Night, people spouting, "Howdy, Neighbor"
I'm headin' down to Dunwich gonna see if I can't unwind,
Hmm mph rmph rm hmm mph rmph rm hmm mph rpmh rm.
So come on down to Dunwich, and meet some friends of mine.

(I can't believe what Kenny says in the actual lyrics - that's the first time I've read them!!!)
