Neil Patrick Harris says the best thing about his two newborn twins with partner David Burtka is making them laugh! The couple welcomed the birth of Gideon Scott and Harper Grace in October using a surrogate. Recently, the hilarious How I Met Your Mother star tweeted about his new favorite audience.

“The tots both started laughing. On the same day,” Harris said, pictured walking with the twins and Burtka. “I’m now obsessed with getting them to do it. Babies laughing is like opium.”
