OK, so, I'm sure everybody remembers Captain Barbosa's disgusting, rotting, green teeth after making a deal with Will Turner and said "Agreed" with that bad hygiene smile? Well, earlier in the movie during the big ship chase between the Black Pearl and the Dauntless, and after the "good" ship gets starboard from dropping an anchor, Captain Barbosa yells "they're starboard!" and turns around to give an order, "get the starboard oars and run out the sweeps" (or something like that)...revealing a sparkling white smile with nice straight teeth and everything. Makeup!
