Nightmare, it's your birthday.
Z bless you this day.
You gave us the gift of some comic relief,
And I'm proud of you today.
Nightmare, it's your birthday!
Happy birthday, Nightmare!
Night, it's your birthday!
Happy birthday, Nightmare!
I wish you love and good will!
I wish you peace and joy!
I wish you better than your heart desires!
And your first kiss from a boy! (or whatever)
Nightmare, it's your birthday!
Happy birthday, Nightmare!
Night, it's your birthday!
Happy birthday, Nightmare!
Yeah!
