Speak when spoken too

There`s something foul with my oral opening
I can not seem to control it,I object to everything.
You know,I`m talking all the time
But I`ve got bupkiss to say
The  ka-ka my vocal cords produce
Even outdid my [bad word] today

Shut up!
Shut up!
Shut up!

Speak when spoken to
Speak when spoken to
Speak when spoken to
Speak when spoken to

Pseudo-provocative,I haven`t got a clue
What I`m refering to,I just argue `til i turn blue
The sound of my own voice gives me
An itellectual high
I get off on my own arrogance
I`m so cynical I could cry

Shut up!
Shut up!
Shut up!

Speak when spoken to
Speak when spoken to
Speak when spoken to
Speak when spoken to

My mouth`s in good shape
My lips are itching
Spare me some duct tape

Blah,Blah,blah,blah,blah
Blah,blah,blah,blah,blah

Shut up!
Shut up!
Shut up!

Speak when spoken to
Speak when spoken to
Speak when spoken to
Speak when spoken to
