Neil Patrick Harris and David Burtka jumped on the Batman bandwagon for Halloween, dressing themselves and their adorable twins up as characters from the comics.

Harris donned a Riddler costume, Burtka was The Joker, and 4-year-old twins Gideon and Harper went as Batman and Robin.

Harris posted a picture of his family on Instagram with the caption, "Happy Halloween from Gotham City!"

The actor and his family always go all out on Halloween. Just last year, they dressed up as classic monsters and Alice in Wonderland characters.

Last week, Burtka and Harris confirmed that they'll both be appearing in episodes of American Horror Story: Freak Show later this season.
