I have been staring at this 1943 Army manual map of ocean currents* for fifteen minutes. Click to enlarge and follow all the swirls and pretty colors.
(I promise you I'm not baked. This is just what we call a "low amusement threshold.")
*It was Fauxhawk who looked up "ocean currents" on Wikipedia. The chief difference between us is that when someone asks "Why is Iceland so warm in the winter?" Fauxhawk looks it up on Wikipedia. I, on the hand, say, "I don't know. It's a mystery" and then eat some cheese.
