This is Gab's tattoo.
"When we grab you by the ankles
Where our mark is to be made
you'll soon be doing noble work
Although you won't be paid
When we drive away in secret
You'll be a volunteer
So don't scream where we take you;
The world is quiet here."
This is the VFD slogan from Lemony Snicket's A Series of Unfortunate Events.
