"The strangest place I ever had sex?" Booth repeated. "The strangest?" He licked his lips as he thought.

The middle of the football field at night? No, not strange.

The cleaning closet at the hockey rink? No, every hockey player has done that.

"When I was a Ranger," He mused, "I took a girlfriend on a tour of the base, and she wanted to see the inside of a tank.. So I guess that might be the most unusual place, though I'm not sure if it's strange."

"The inside of a tank?" Brennan stared, as Booth continued to squint at the ceiling above him, clearly searching for something more unusual.

"It was decommissioned." He added absently. "A relic."

Brennan was beginning to have a headache from keeping her eyebrows raised.

"I had sex in a cemetery once." He said suddenly.

"What? When we were in New Orleans..." She began.

He waved dismissively at her. "Sex in a cemetery is different than sex in a makeshift morgue with fresh dead everywhere." He paused. "Though I did have sex in a real morgue once.."

"And you don't find that stranger than in a decommissioned tank?"

"I forgot about it I guess. I was dressed as a Private Eye.." His voice trailed off. "So, what about you?" He asked brightly.

"The ruins of an ancient brothel in Rome."

"Fun. I'd like to go to Rome." He smiled. "To see the catacombs."

"To see them? Or to have sex in them?" Brennan asked darkly.

"That would depend on who I'm with."

"A cute tour guide."

"Nah, I have to be REALLY into someone to have sex among the dearly departed. Like, long term relationship serious."

"Would you have sex with ME in the catacombs?"

"Is that one of your nine questions?"

"No."

"Then I'm not answering that. Next question please."
