I've been re-watching S1 over the last two days and I picked up some fun, "Did you know?" trivia bits. . . Opie (Ryan Hurst) was in Saving Private Ryan, he was the guy who actually knew where Pvt. Ryan was, the guy with the hearing problem. That beard makes him unrecognizable. In the episode where they find the buried skeletons, and one of them is Lowell's (the junkie mechanic) father, Jax says something about Hale "pouring poison in Lowell's ear". It's the only time that I've noticed that there is a reference to the story of Hamlet, being that poison in the ear was how Hamlet's father, the King, was murdered. . . spoiler alert.
A very meta reference with SoA being loosely based on Hamlet. And if you were curious about Chibs' scars, he got them in a bar brawl in Glasgow. Yeah, that really happened, it's called a Glasgow Grin.
