Thor: Ragnarok director Taika Waititi wished Thor actor Chris Hemsworth a happy birthday on his Instagram. However, it’s not just a simple birthday. Nope, the Instagram message shows Hemsworth flipping off Waititi the middle finger. Waititi, himself, is dressed in his motion capture gear to bring to life Korg.

Waititi included the following message, “Happy Birthday Chris Hemsworth! Thank you for being so cool to me and such a supportive friend. So rare to find a connection like ours. Xo.”

The Thor: Ragnarok cast are no strangers to having fun. Hemsworth posted a photo of the cast and director back in July describing them as a “band of misfits.”

Thor: Ragnarok storms in to theaters on November 3, 2017. It stars Chris Hemsworth, Mark Ruffalo, Cate Blanchett, Tom Hiddleston, Idris Elba, Tessa Thompson, Karl Urban, and Jeff Goldblum.
