Thursday morning, seven hundred hours. The job is at hand: hop in the kayak, nip down to the Antarctic, a spell on the Wurlitzer, harass some randy Great Whites, brave the huge swells of the Southern Ocean, nibble on some blubber, chuck some rocks at the penguins, string up a couple of tennis racquets, sing a couple of show tunes, evade some icebergs, ponder the fate of Schrödinger's cat, zig-zag through the squalls, step aside for a quick shandy, head back up the Derwent, and in to work! Are you up for it, or are you YELLOW? Theme Thursday . Like Theme Tuesday, only on Thursday.
