JOE is so disoriented by his disease, he goes in the other room and plays the title cut from an old Jeff Simmons album, and sings along with it.

Joe:
Lucille
Has messed my mind up
But I still love her
Oh I still love her
Lucille
Has messed my mind up
But I still love her
Oh I still love her
Lucille
Has messed my mind up
But I still need her
You know I need her
Whatcha tryna doota me
Lucille?
Whatcha tryna doota me
Lucille?
Whatcha tryna doota me
Lucille?
You got me goin' outa my mind
Lucille
Has tore my heart up
But I still love her
I really love her
Lucille
Has tore my heart up
But I still need her
You know I need her
She treats me like my heart
Is made of stone
She runs around
And leaves me home
All alone
She doesn't answer
When I call her on the phone
She messed up my mind
I'm crying alla the time
Lucille
Has messed my mind up (etc., etc., etc.)

Central Scrutinizer:
This is the CENTRAL SCRUTINIZER...again, Hi!...It's me again, the CENTRAL SCRUTINIZER...Joe says Lucille has messed his mind up, but, was it the girl or was it the music? As you can see...girls, music, disease, heartbreak...they all go together...Joe found out the hard way, but his troubles were just beginning...his mind was so messed up...he could hardly do nothin'...He was in a quandary...being devoured by the swirling cesspool of his own steaming desires...the guy was a wreck...so...what does he do? For once, he does something SMART...he goes out...and pays a lot of money to L. Ron Hoover... at the First Church of Appliantology!
