I had to stop him from arresting an old lady who let her dog urinate against the fire hydrant that was in front of Burgerville headquarters."You'll blow our cover.""But what if there is a fire?""The fire department will come and put it out," I said."With what?""Water," I said."Not from that hydrant," Monk said. "It's inoperable.""No, it's not," I said. "It can still be used.""There is urine all over it," Monk said. "no fireman would dare touch it, nor would any other human being.""Firefighters run into burning buildings," I said."They aren't going to care about some dog pee on a fire hydrant.""They would if they knew," Monk said. "We should call and warn them. Call Joe right now. He can get the word out faster than we can.""Every fire hydrant in the city has dog pee on it, Mr. Monk. It's how dogs mark their territory. I can guarantee you that every male dog that has passed that hydrant has pissed on it."He looked at me, wide eyed, "No.""It's what dogs do," I said. "The firefighters knows this."Monk swallowed hard. "And they still use the hydrants?""Of course they do.""They are the bravest men on earth," Monk said solemnly.
