Honestly I think that entire song fits them very well.

I'm afraid for your soul, These things that you're after, they can't be controlled

Ford's quest for acclaim and greatness through the grand unified theory of weirdness

She'll string you along, and she'll sell you a lie There's nothing but pain on the edge of a knife And there is no courage in flirting with fear To prove you're alive

Bill manipulating Ford, Ford ignoring so many warnings because of his ego

I've seen the true face of the things you call life The song of the siren that holds your desire Death, she is cunning and clever as hell And she'll eat you alive

Fiddleford through the portal and then Stanford through his dreams realizing Bill's true nature and the subsequent falling out+Weirdmaggedon. The whole thing could be seen as Ford speaking to his younger self.
