I was a sinner, a real bad kid.
What thou shalt not, I shalt did.
Neighbors cat I tried to neuter,
took a wiss on the school computer
He took a wiss oh yes he did!
Now I've changed you can't deny,
so come on up...and testify!
Testify, testify, come on up and testify!
My hip's misbhavin'
Testify!
Got a nicotine cravin.
Testify!
There's a cramp in me glavin'
Testify, testify, testify!
My glasses make me look like a geek.
Now you'll get the girls you seek!
Will see you at makeout creek.
Bart's the boy of the hour, he's got the power.
So raise your voice and don't be shy,
test-a, test-a,
Test-a-fy! Come on up and testify!
