Peter, Peter, Pumpin-eater, had a wife and couldn't keep her, put her in a pumpkin shell, and there he kept her very well...

"You're kidding me, right?" Booth looked hopeful.

"No." Cullen shook his head. "Peter Piper was found dead in a peck of pickled peppers."

Booth sighed and closed his eyes in agony. "Sir.."

"I know. But it's true." Cullen passed over the file. "Peter was 38 years old, single.."

"Suspects?"

"He had a fight with his girlfriend, Miss Mary Contrary, in her garden. Neighbors reported it. You can start there. I think she's married now."

"And you're positive on the ID?"

"He was perfectly preserved."

Booth groaned again. It was cases like this, where he just knew Bones was going to be trouble….

It was looking like a nursery rhyme mess...

~B~

"Bones, Let's go." He strode into Angela's office, interrupting their morning coffee break.

Brennan smiled. "Remains?"

"Already identified, but I need your help anyways."

"So, no face for me?" Angela raised her eyebrows.

"Not yet. Peter Piper was perfectly preserved." Booth cracked a smile. Knowing Angela would get it.

She did.

"In a peck of pickled peppers?" She smirked.

"Actually… Yes." Brennan looked up the file she'd taken from Booth. "How did you know?"

Angela's jaw dropped open. "Seriously?"

"Yup." Booth shifted. "We have to go interview his girlfriend."

"Oh." Angela smiled. "Little Bo Peep?"

"Miss Mary Contrary." Brennan supplied, shutting the file.

Angela raised her eyebrows.

"She's married now." Booth sighed. "To Georgie Porgie."

There was a snort, and Angela dissolved in giggles, sliding down in her chair, her shoulders shaking.

"Are you ok Ange?" Brennan asked in alarm.

"Fine Sweetie." Ange waved them away, still giggling.

"Come on Bones, it's an hour's drive to Nursery Lane." Booth guided her out, grinning at the sound of the now hysterically laughing artist.

"What's wrong with Ange?" She asked him as he wrapped his arm around her shoulders.

"I'll explain it in the car."

~B~

"So let me get this straight." Brennan held up her hand a ticked off points on her fingers. "Peter Piper was found deceased in a peck of pickled peppers. There is a nursery rhyme in which a Peter Piper picked a peck of pickled peppers. Mary Contrary is also a nursery rhyme character?"

"Yes." Booth nodded, she seemed to be getting it now, it had only take half an hour.

"What about Georgie Porgie?"

"Georgie Porgie, Pudding and pie, kissed the girls and made them cry, and when the boys came out to play, Georgie Porgie ran away." Booth half sang.

Brennan frowned. "Why?"

A line creased Booth's forehead. "Why what?"

"Why did he run away? And why wasn't he in school? And why.."

"It's a nursery rhyme Bones!" Booth interrupted.

"So it doesn't have to make sense?"

"No."

"But.."

"It was written over a hundred years ago!" He explained.

"But Mary Contrary is married to Georgie Porgie, and they might have killed Peter Piper."

Booth couldn't resist. "I've got my money on Jack Horner, he always seemed to be a twit to me."

Brennan stared at him blankly.

He sighed again. "You know, it's times like this I wish Angela was with us."

"Why?"

"She'd think that was funny."

Brennan picked up her phone, put it on speaker, and dialled Angela.

"Hey Ange, Booth says he think maybe Jack Horner did it."

There was another snort.. More giggles.. "But he's always in the corner!" She gasped for air, "What about Peter Pumkin-eater?" There was more hysterical laughter... "If you meet him, tell him to call me, I'm available!"

The line disconnected as Angela dropped the phone and laughed till tears ran down her face.

In the car, Booth was trying to swallow his laughter, but it was burbling out in snorts and glurks, while Brennan stared at him.

"Who is Peter Pumpkin-eater?" She finally asked.
