Watch Drew Barrymore surprise Maisie Williams with baby pigs on her talk show: 'This is the best day ever'

The "Game of Thrones" star missed out on a school trip to a pig farm because she had to audition for the HBO series.

Drew Barrymore went hog wild in order to complete a childhood dream for Maisie Williams. 

The daytime host transformed her show’s set into a literal pig pen — with a barnyard backdrop and all — after learning that the actress missed out on a school field trip to a local pig farm in order to attend her Game of Thrones audition. 

“I said to my mum, ‘You think we could just miss this one and go to the pig farm instead?’” Williams told Barrymore about the experience. “Thank god she said let’s not! Like, 'Let’s go to the audition.' But I missed out on the pigs and it’s really, really affected me in my core ever since.”

“I want to thank your mother because we needed Arya Stark in the world,” Barrymore replied, before revealing that she happened “to have an area full of piggies” for them to play with after the commercial break.

When the show returned, the pair, accompanied by animal expert Stephanie Arne, sat on haystacks as they fed treats to three adorable little piglets and played a pig-themed version of Barrymore’s “The Final Five” segment.

“This is the best day of my life,” Williams gleefully remarked.

Playing upon Game of Thrones’ dire wolves, Barrymore then proceeded to ask Williams what she’d name a dire pig if given the chance. “My favorite thing to do is give them super human names,” she replied. “So I would call her Claire.”

The New Look star was also later asked “when was the last time you felt happiest as a pig in you-know-what?” To which she perfectly answered, “Right now, Drew, with you.”
