A sick day a sick day
I'll not make it all year
My class is all here
Down to each little sneer

A sick day a sick day
I'll not make it all year
Those cute little creatures
Have nothing to fear

A sick day a sick day
I'll not make it all year
Still knowing that teacher's
not entirely all here

A sick day a sick day
I'll not make it all year
Each little tear
Makes it perfectly clear

A sick day a sick day
I'll not make it all year
A day off is coming
And hopefully near

a sick day a sick day
I'll not make it all year
It's harder and harder
Maintaining my leer

A sick day a sick day
I'll not make it all year
Perhaps my behavior's
becoming quite queer

A sick day a sick day
I'll not make it all year
Perhaps in the morning
I'll call in and cheer

A SICK DAY A SICK DAY
I GOT A PAIN IN MY EAR

Alas...I can hear my principle sneer
With a resigning smirk easy to hear
NO SICK DAY NO SICK DAY
SORRY MY DEAR

NO SICK DAYS NO SICK DAYS
REMAINING THIS YEAR
