Ben Affleck is the newest heir to the throne of Batman, and apparently used his acquisition of the superhero's costume to pull an awesome dad-stunt for his four-year-old son Samuel: Affleck's ex-wife Jennifer Garner confirmed to Extra last Friday (Mar. 4) that the actor showed up to his son's birthday party dressed as the dark knight, much to the shrieking delight of all children in attendance. 

“We all dressed up, I dressed up as a ninja and Ben dressed up as Batman for Sam,” Garner said. The actress heaped praise on Affleck's surprise, calling it "the best dad moment in history.” The actress' praise for Affleck should be taken seriously, given the millennia of dad-history already etched into the sands of time.  

Affleck is primed to carry the mantle of the Batman saga when Batman Vs. Superman: Dawn of Justice hits theaters March 25. He'll star alongside Henry Cavill as Superman, Jesse Eisenberg as Lex Luthor and Gal Gadot as Wonder Woman.
