Well, maybe not, but the family of four looked adorable, decked out in Alice and Wonderland themed costumes on their way to a Halloween party in Studio City on Saturday, Oct. 19.
The How I Met Your Mother star and Burtka dressed as Tweedledee and Tweedledum, looking the part and wearing bright yellow shirts, blue bowties, white vests and red caps.
Harper went as Scary Alice, resting on Burtka's shoulders, and donning a light blue dress with white trim, a black headband and face paint. Gideon, who was held by Harris, was the White Rabbit, sporting a vibrant red jacket.
No Cheshire Cat?
Dressing up for Halloween is a big tradition for this group, and this is the third year in row that they have decided to portray characters from famous classic movies. Last year, it was The Wizard of Oz (with Harper as Dorothy, of course) and in 2011, it was Peter Pan (Burtka was Peter Pan while Harris went as Captain Hook).
