Who: Euram and Sigurd
When: Really backdated!! Back when Sigurd's arm was still in a cast and obviously before he left and...yeah awhile ago.
What: Sigurd decides that Euram needs a hobby to stop being a ball of emo angst and offers to teach him knife throwing. It goes about as well as you'd expect.

If the point is not to hit the tree then why is that where you told me to aim? )
