That children's book bit is still one of my favorites. Very first page is grammatically incoherent, and you can super easily tell when he started to lose interest in his illustrations.
That and setting off a flashbang in his own face. That clip is incredible.
The clip of him killing the vet in red dead is actually so fucking scary, imagine if you were him and Arthur hugged you and then a few seconds later, wordlessly, for no discernabile reason,started shooting trigger happy and chased you down and fucking pistol whipped you to death
2:15 The ADHD spaz forgets where he left his gun and immediately blames and executes the sad guy with one arm that just got a hug for the first time in his life. Classic Jerma
Jerma clips for the mentally unwell (looking at YOU)
