David Burtka neil patrick harris stripes hat school costume dragon

They are so cute we just want to put them in our pocket!

Neil Patrick Harris and David Burtka's adorable twins, Harper Grace and Scott Burtka-Harris, got into the spirit of things when they got all gussied up on Halloween in Los Angeles.

Harper Grace went as Rapunzel from Disney's Tangled and lil Scotty went as a plush dragon. We can't tell which costume we like better -- so don't make us decide!

The How I Met Your Mother wasn't there for the errand run, only his 38-year-old partner was, but we certainly hope the entertainer got to see his little ones in their full Halloween glory!
