I remember Neil Casey as the CPA who loses his shit while trying to do Ilana's taxes on an episode of Broad City. He is really good at playing seemingly normal guys who slowly slide into batshit craziness. "I didn't know Killian Casey…I didn't know"(in Irish accent) It was hilarious!

Someone may have already mentioned it but I really enjoy the opening to The Vikings. The song has a haunting quality and the visuals of the warriors and their weapons drifting to the bottom of the sea to be met by the beautiful valkyries is wonderful.
