The third chapter of Akatsuki Bloopers!
Your voice of Reason.
"Itachi... What the hell are you doing?" Kisame peered into Itachi's room. The Uchiha was wearing glasses and dissecting a rabbit.
"What does it appear I am doing?" Itachi asked, not looking up from his work.
"But why are you doing it?" Kisame asked, walking into the room.
"To see if it ate my contacts."
Kisame gaped.
Nara : Yes, I know. It was short. Bite me.
Itachi : I do not wear contacts! (Something falls out of his eye and lands on the ground.)
Nara : You sure?
I am there, but you don't see me.
I give you advice, but you don't know me.
And I will drop by to see you again.
For I am Your voice of Reason.
