In House of Cards, there was an interesting scene:
"The hot water will open up your capillaries. The aspirin you just took will make your blood thinner. It's up to you, Peter," Frank says, taking out a razor and putting it on the bathtub. "Oh, and if you do decide to take the coward's way out, cut along the tracks, not across them. That's a rookie mistake."
Before learning about SN, that was my favorite one, although SN still takes longer before losing consciousness and dying than bleeding out with the right kind of cut can.
