Quote from : The Titan's Curse Book

Let us find the dam snack bar," Zoe said. "We should eat while we can." Grover cracked a smile. "The dam snack bar?" Zoe blinked. "Yes. What is funny?" "Nothing," Grover said, trying to keep a straight face. "I could use some dam french fries." Even Thalia smiled at that. "And I need to use the dam restroom." Maybe it was the fact that we were so tired and strung out emotionally, but I started cracking up, and Thalia and Grover joined in, while Zoe just looked at us. "I do not understand." "I want to use the dam water fountain," Grover said. "And…" Thalia tried to catch her breath. "I want to buy a dam T-shirt." I busted up, and I probably would've kept laughing all day, but then I heard a noise: "Moooo." The smile melted off my face. I wondered if the noise was just in my head, but Grover had stopped laughing too. He was looking around, confused. "Did I just hear a cow?" "A dam cow?" Thalia laughed.
