Punisher goes to confession(!) where the priest tells him about another parishioner’s confession(!) of multiple murders. Punisher kills the dude who confessed, based on what the priest told him.
The showdown is in a wax museum where we see Marilyn Monroe and Ronald Reagan, among others.
I like the idea of other people who see Punisher regularly weaponizing him and feeding him information—it makes his one-man war on crime more believable.
