David Harbour cannot say this 1 simple word in hilarious 'Stranger Things' blooper

David Harbour is an accomplished, professional actor with 17 years' experience in the business.

But that doesn't mean he can make it through a scene where he's required to say the word "grandma" without totally cracking up.

To celebrate hitting the 500,000 follower mark on Twitter, the official Stranger Things writers' account shared a clip that they described as "the Duffers' favorite bloop from s3."

Without spoiling anything, it's from the scene in which Hopper tries to get rid of Mike, who he's worried is spending too much time with Eleven.

oh wow i can’t believe we get to share all the love and laughter with 500,000 of you!!

it’s been a fun ride and y’all are so amazing that we’re going to celebrate with the Duffers’ favorite bloop from s3!
