This one is so obvious, I don't know how it got by! In the episode where Ashley gets all depressed because of Taylor's girlfriend, Megan, and Mary-Kate get a pigeon, Harriet, Ashley gives Harriet a pedicure with PINK NAIL POLISH. When Harriet is bought again by Carrie and brought home, Carrie says "Now don't be surprised if she looks a little different, she has been through alot" Mary-Kate says "I'll say, her nail polish is all chipped!" Carrie replies "Nail polish?!?" and they do a close-up on Harriet. Pink nail polish? Her nails were clearly black, as a normal bird's. There was no nail polish on ANY nail, not even chipped polish! They should have noticed that in editing and at LEAST added it in via computer!
