Gonna call you at home
On the telephone
I'm gonna be real nice I'll tell you
And offer you some advice

How do you know?
How do you know?
Mother fucking

Gonna send you a letter
With the wrong date
And it's going to confirm my fears
That it'll land on my special day

How don't you know?
How don't you know?
Mother fucking

Been on this call
Music in my ears
And it's going to confirm my fears
That you know nothing at all

How do I know?
How do I know?
Mother fucking
