It should come as no surprise that the Neil Patrick Harris-David Burtka clan were once again the undisputed champs of celebrity family Halloween costumes. This year the actor (and now author) revealed this year’s ensemble on Twitter and Instagram, with the caption “Happy Halloween from Gotham City!!”

NPH went as a dapper Riddler, while husband Burtka channeled a Jack-Nicholson-era Joker. Their twins dressed as Gotham City’s superheroes, with Gideon as Batman and Harper as a very fierce-looking Batgirl—criminals beware!

Elaborate group costumes are a tradition for the Harris-Burtka crew. Last year, the foursome took their cue from Alice in Wonderland, and the year prior to that, The Wizard of Oz. All other celebrity families, take note: Step up your costume game.
