Barney: How long have you been married, Mr. Franklin?
Franklin: All my life.
Barney: Look, look, Shriker. Mr. Fuzzo here has a hansom cab. And he needed a horse.
Shriker: Didn't he know that?

Fish: When Bernice and I were courting, we used to ride a lot in a hansom cab.
Wojo: I'd rather walk around the park. Uh, it's healthier.
Barney: May be healthier, it's not safer.
Fish: We'd sit there and hold hands and I couldn't help thinking, looking at the back end of that horse, 'Is he trying to tell me something?'
Barney Detective Wojciehowicz is going send out an APB on the missing animal. Do you have a description?
Wojo: Oh, yeah: Brown eyes, brown hair, two white stockings, stands about 6' 3", and weighs about 1,200 pounds. Hey, Barn? Whadya say we don't tell 'em it's a horse?
Barney: I think you better tell them. They may come up with somebody.
