That's what friends aren't for

Hey, buddy.
Do me a favor.
A trusted comrade stuck a knife into my back.
Do me a solid and remove it?
It's hurts horribly.
It's making me self-conscious.
I'd appreciate it.
Eh?
What's that?
Why did they do it?
No idea.
I mean.
I'm not sure.
Let's see.
Yeah.
I'm drawing a blank.
I mean.
They stuck a knife in my back.
But yeah.
I'm bleeding.
Help.
