In the clip, an unsuspecting Leslie approaches their fridge to retrieve a Brita filter to find that Harington replaced the milk with a decapitated replica of his head.
In an interview on The Jonathan Ross Show last week, Harington revealed that his proposal didn't go as planned. He started by showing a video of Leslie's reaction: Completely unaware, she opens the fridge and looks around before suddenly starting to scream uncontrollably, run away, and fall on the floor.
"It didn't go down well", Harington confessed.
Apparently, the Haringtons take April Fools' Day VVV seriously, so he made a decision to put a fake decapitated head in his refrigerator for his love, Rose Leslie to find. "There is absolutely no chance of me convincing [Leslie] of that", he explained. He didn't exactly ease her into the whole April Fools' thing. "And after that, she was in tears, and I was there going, 'April Fools.' It didn't go down well".
"My family does April Fools","Harington said. And I think that's marriage included".
