this guards movement of anything

Well, it's really funny
The movement of the fingers of the right hand
I've noticed it many times already
Well, there's a holster and a baton.

And the scene with variations is this:
A big guard is talking to a little crazy old lady,
But he does this movement with his fingers.
What kind of gamma musician is this?
I'm left-handed, what a surprise.

Tugging someone's death from the sheath by the handle,
Hanging as it should be on the left side.
You're quoting yourself again.
Sorry Ouija, I'm already a little drunk.

I just find their warning movement of their fingers during conversations funny.
The old lady is unarmed and does not attack, but these people do it anyway.
Maybe they were trained in old Italian westerns.
And if grandma turns out to be a faster cowboy than you?

What's the name on the grave with gold, Blondie?
I can't remember. Asper?
Why do you need an internet idiot?

a noose around your neck. Name!?

I forgot. We've already dug up the gold.
Give me the name anyway.
Blondie, damn you, shoot off the rope!
