The transportation needs of working girls

We're on a bus. The working girls are heading to work, each one is wearing a little red necktie. They are carrying their briefcases and their ipods. The duck is reading the "Daily Quack". She's about to eat a corn cob and we can see that she's carrying more corn cobs for her lunch. But wait, isn't that a pig in the other seat -- he's not a working girl wearing a little red necktie -- and he's stolen one of her corn cobs!
