Haney's Got A Gun
If that isn't the worst pun you read today, I am truly, truly sorry. Anyway, from the fourth-wall-shattering Brave and the Bold #124:
That, my friends, is Bob Haney grabbing his rifle to take on a gang of terrorists who, without even the merest attempt to explain how, are simultaneously battling Sgt. Rock and Batman in a story by Haney and Jim Aparo, and also Haney and Aparo themselves.
Because Bob Haney, that's why.
