[Seth MacFarlane (as himself)]
Oh, my head is filled with voices
And they never go away
There’s a baby kind of British
An alien real skittish
(Stewie: And might be possibly gay)

[Seth MacFarlane (as himself)]
My head is filled with voices
And the doctors don’t know why
For a second, I’m a normal talking regular gent
But next, I’m George Takei

[Seth MacFarlane (as George Takei)]
You know eh, after I came out of the closet
They… they wouldn’t let me touch the Captain’s log

[Seth MacFarlane (as himself)]
Oh, my head is filled with voices
As I do my monologue
From a normal conversation
There’s a sudden transformation
To a jеlly droopy old dog

[Seth MacFarlane (as a jelly droopy old dog)]
You know what?
Mitt Romney just makes me so mad
[Seth MacFarlane (as himself)]
Oh, my hеad is filled with voices
No, the doctors, they don’t know why
For a second, I’m a normal talking regular gent
But next, I’m Marty McFly

[Seth MacFarlane (as Marty McFly)]
Well, Doc, you can’t just walk in a store, and…
And buy plutonium
Would you rip that off?

[Seth MacFarlane (as himself)]
Oh, my head is filled with voices
It’s a mental kind of fog
As often as I try it
It’s hard to keep them quiet
(Kermit: And I talk like Kermit the Frog)

[Seth MacFarlane (as Kermit the Frog)]
Uh, you know, it’s really great to be here in Manhattan
I love being in New York, uh, except for all the Jews
Yay!

[Seth MacFarlane (as himself)]
Yes, my head is filled with voices
It’s a special kind of hell…
But tonight, it’s all completely okay…
‘Cuz this is S-N-L!
