I was a sinner, a real bad kid
What thou shalt not, I shalt did
Neighbor's cat I tried to neuter
Took a wizz on the school computer
He took a wizz, 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 misbehavin'
(Testify!)
Got a nicotine cravin'
(Testify!)
There's a cramp in me Glavin'
(Testify, testify, testify!)
Testify, testify, come on up and testify
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-i-fy!
Testify, testify, come on up and testify
