I think it's bullshit that if you remember lines from "The Simpsons", "Seinfeld", "Star Wars", etc. then you are a derivative, uncouth NERD. But if you quote someone who is dead, then you are LITERARY.
To add some culture to my nerdy persona, I'm learning a new quote per week for the year (or Lent, depending on laziness). This week's is courtesy of St. Patrick's Cathedral in Dublin, from one of my favorite writers (also a longtime head of the cathedral and general smartass).
"We have just enough religion to make us hate, but not enough to make us love one another." Jonathan Swift
