Ah, but it WASN'T an issue. It was at least two. And the villains were demented dwarves who sawed mobsters off at the knees. (And thought Wolverine was one of them because he's short)
I always thought this was Ennis' fuck-you response to an editorially-mandated Wolverine guest appearance. I do know he hates the character, judging by how he treats him every time he comes near him. But then too, he did something similar to this to Cassidy once.(the mobster that shoots pieces off him and watches them grow back) Does Wolverine actually call himself the "Canucklehead?"
But still: the moment when Wolverine gets his face blown off, and the moment he gets trapped under the steamroller, are both totally worth it.
