Childish gay joke aside, this doesn't even work as a response to Ennis' Wolverine; Ennis wrote a mean-spirited but completely accurate (and most importantly, very funny) parody of all the worst Wolverine tropes. The fact that the character lost a fight to the Punisher was besides the point. Here, Tieri doesn't write parody, he just has Wolverine describe the essence of the Punisher's character. The Punisher is a psychotic waging a futile war on crime. That's the point. Tieri just points out the obvious and impotently has to resort to a nonsensical gag to provide a "joke".
