Punisher (2001 Series) #16

Vertical Challenge. Two of comics' toughest butt-kickers collide when Wolverine and Punisher unite in this Marvel Knights event! The Punisher investigates a rash of mob maulings which involve cutting the bad guys off at the knees. His search leads him to Wolverine, who is investigating the same case; of course, the two battle and the Punisher blows Logan's face off. Their fight is halted by the actual culprits of the leg removals, a pack of, to be politically correct, little people.
