The second image is a sophomoric joke. I hope it will make sense in context. Friedrich Nietzsche is the philosopher who wrote, "Whatever doesn't kill me makes me stronger."
I take strong exception to Toxic Positivty in the post I'm writing. The phrase "Friedrich Nietzsche ist untoter," means he's "undead." Like a philosophical zombie...
I made it grafitti, cuz, well, Banksy blows my mind.
