Haha I remember that episode, bloody hilarious 

We also see the extreme difference in the brothers from this picture. Stan as always relied on brute strength, but has never had the need to actually kill a man, which is why he has brass knuckles. Ford, on the other hand, has always had to rely on his wit. I think when he was thrown into that portal, he decided he needed to learn to defend himself better, so he became aquatinted with firearms.
