David Harbour has a really hard time saying “grandma.”
On Tuesday, the “Stranger Things” writers’ room Twitter account shared the Duffer brothers’ favourite blooper from season 3.
“Your mom called,” Harbour says in the clip. “She needs you home, right away.”
“Is everything okay?” asks Finn Wolfhard, to which Harbour responds, “No, I don’t think so. It’s your grandma,” before cracking up laughing.
Through multiple takes, the word “grandma” keeps setting Harbour off laughing.
“The word is so funny!” Harbour says at one point as Millie Bobby Brown says, “I can’t do this,” wiping tears from her eyes due to all the laughter.
The official “Stranger Things” Twitter account also teased that more bloopers from the season are on the way Nov. 6.
