“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."...I started cracking up, and Thalia and Grover joined in, while Zoe just looked at me. "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 need to use the Dam Bathroom, I need to use the Dam Snack bar, I want a Dam Tee-Shirt.”

“Hoover Dam," Thalia said. "It's huge."We stood at the river's edge, looking up at a curve of concrete that loomed between the cliffs. People were walking along the top of the dam. They were so tiny they looked like fleas.The naiads had left with a lot of grumbling—not in words I could understand, but it was obvious they hated this dam blocking up their nice river. Our canoes floated back downstream, swirling in the wake from the dam's discharge vents."Seven hundred feet tall," I said. "Built in the 1930s.""Five million cubic acres of water," Thalia said.Graver sighed. "Largest construction project in the United States."Zoe stared at us. "How do you know all that?""Annabeth," I said. "She liked architecture.""She was nuts about monuments," Thalia said."Spouted facts all the time." Grover sniffled. "So annoying.""I wish she were here," I said.”

“Like water leaking through a dam," said Piper."Yeah," smiled Percy. "We've got a dam hole.""What?" Piper asked."Nothing," he said. "Inside joke.”

“Before I could respond, Thalia tromped up the stairs. She was officially not talking to me now, but she looked at Grover and said, "Tell Percy to get his butt downstairs.""Why?" I asked."Did he say something?" Thalia asked Grover."Um, he asked why.""Dionysus is calling a council of cabin leaders to discuss the prophecy," she said. "Unfortunately, that includes Percy.”

“Our ideas held no water but we used them like a dam.”
