Conductor: Tickets, please. Oh, wow, is that a parrot?
Lady with parrot on her shoulder: Yes, it is. I take him out every mother's day to see my parents. He's on a leash, though, and won't make any noise.
Conductor: Okay, no problem. There's actually a cat in the next car and a dog in the one after that.
Parrot lady's kid: A cat in the next car?! Cats eat birds. One animal per car!
Conductor, deadpan: I've got bad news for you, kid–there's more animals on this car than just that parrot.
