You gotta face it: this guy is wacked:
He gets tense and nervous, and then he's hacked.
He sees shes, and then his mind's on fire. . .
Can't touch girls 'cause of Mother's ire.

"Psycho," killer,
Qui est ce Bates?
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Croak, croak, croak.
"Psycho," killer
Qui est cette bête?
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Croak, croak, croak.
Ay-yi-yi! Nuts!

He would like fornication;
Ma won't let him dip in it.
He's stalking and hot,
But he's not laying anyone.
Then he gets someone to slay:
Her fate is sealed.
Slays someone once;
He will slay again.

"Psycho," killer,
Qui est ce Bates?
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Stroke, stroke, stroke.
"Psycho," killer,
Ay, quelle bête!
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Stroke, stroke, stroke,
Knife, knife, knife nut!

Ce film est blanc et noir; le
Coût de blanc et noir, le
Moins. Aussi, pas de mouchoir
Dois tu avoir pour le voir.
(Français en chanson--pourquoi?)

Though he's slain, he's not unkind--
His crazy, creepy ma's not polite.

"Psycho," killer,
Qui est ce Bates?
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Bloke, bloke, bloke
"Psycho"'s kilter
Way off--très!
Ja-Ja-Ja-Ja-Ja-Ja-Ja-Ja-Janet met 'er
Maker; she had run-run-run away.
Bloke cloaks, cloaks. . .mum's
Nice, nice, nice coat. . .nuts!

Bloke cloaks, pokes, strokes; folks croaks.
