Mayflower: Say, man, since when is it a crime to come to the defense of a lady and try and protect her honor? Since when?
Harris: When you push her trick out of a second-story window.
Fish: (on the phone to Mona) Now, I'm going to give you some advice. Next time call Madison 8-5642. (hangs up)
Barney: That's the Fire Department!
Fish: She's in heat, isn't she?
Barney: Nick, where do we keep the office supply vouchers?
Yemana: Look in the file under O. Or S. Or V. If not, then M, for miscellaneous. And if you don't find it in M, they're lost.
Barney: Then I look under L?
Yemana: Good a place as any.
Barney: Did you ever wonder why the sperm whale, which is the largest mammal on the face of the earth, has a throat about that size? (forms a circle with his thumb and fingers)
Chano: Yeah. You know, I always did wonder. Why is that?
Barney: Because that's the way it is. And there ain't anything you can do about it.
