“I need to use the Dam Bathroom, I need to use the Dam Snack bar, I want a Dam Tee-Shirt.”

“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.”

“Whats my title? Am I admiral or captain or-" "Repair Boy!" "Very funny Piper.”

“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.”

“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.”

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

“If I could dam up the flow of Duck River channel its waters into my inkstone pool I'd use it up expressing my congratulations and I could celebrate your birthday forever.”
