I think we were past the point of humor during that particular episode but there was a reason it was named like it was.

if it wasn't an Arnie reference, could it have been a Stand By Me reference, "Chopper, sick balls"? or Eric Bana's Chopper: "if you keep stabbing me, I'm gonna die"?

clearly, i'm the type where everything is a movie reference, or it's a missed opportunity

whose chopper is this?

It's Zed's
