First, a big round of applause for my beta, Bodiechan, without whom none of this would be possible ;)

I'm a bit ashamed to admit this, but, this fic was very mildly inspired by Roger Bart's back injury when he missed those few weeks of shows when Young Frankenstein was still on Broadway (and I mean mildly. The causes are not the same at all... I hope. Does anyone know what actually happened to his back?). I have no idea where it came from, really! :P

Anyway, enjoy!

Disclaimer: I don't own anything. If I did, I'd be as cool as Igor and as crazy as Froderick ;P

"Hm, dat vas nice," Inga purred, snuggling closer to Frederick's warm, bare chest. "I did not zink I vould be able to go for round three, but you just vent right for it, did you not?"

Frederick nodded stiffly, his face slack. He knew the tenseness in his body would give away what he'd been hiding from Inga since "round three"... he just hoped she wouldn't notice. Frederick shifted his position slightly and almost let out a grunt of pain.

"I mean, it may not seem like it, but you can be very forceful sometimes." Inga continued, oblivious to his discomfort. She sighed happily, "I love you, my darling doctor."

He just nodded again, the same as before.

"Frederick?" Inga raised her slightly-mussed blond head to stare at him curiously. "Vhat is de matter?"

He looked surprised. "Hm, what? Oh, nothing darling. Nothing at all."

"Are you certain? You look like... like you are in pain."

Frederick laughed loudly, wincing as he did so. "Don't be silly, Inga! I'm not in pain! Why in the world would I be in pain?" Like he needed to prove it, Frederick sat up quickly, only to fall back against the pillows, a groan escaping his lips, "I'm in pain!" A fresh sheen of sweat broke out across his forehead.

"I knew it!" Inga exclaimed. She shot up, yanking a sheet with her to cover up. The jostling movement caused Frederick to groan again.

"Oh no!" She cried. "Vhat did I do?"

"No, no. It wasn't you," Frederick assured her, trying to move lightly to see if that would eliminate the pain. It just made it worse. "Okay, okay.... maybe it was you!"

Inga stared at him worriedly, her hands wringing themselves without her fully realizing. "Vhat do you zink it is?" she asked nervously.

"I... I'm not sure... but I think... I may have thrown my back out." If it could have, his face would have flushed with embarrassment. His back was killing him. Even lying down, a heavy burn radiated downward into his legs.

Inga quirked an eyebrow, "You... threw your back out during sex?" She bit down on her lower lip to keep herself from laughing.

He frowned at her and tried to sit up, but fresh pain seized him and he gasped out loud. "Yes, okay! Yes! I threw my back out during sex!"

Inga stuffed her fist into her mouth, but that didn't stop the giggles from bubbling out. "Oh, Doctor! You are getting old!"

"Thirty-two is not old!" he whined. Tears were beginning to prick at the corners of his eyes because of the pain, but he blinked them away.

Inga chuckled as she moved to run a hand lovingly through his crazier-than-usual fly-away hair, but Frederick shouted, "No! Don't touch me!"

She recoiled almost instantly, "Vhat do you vant me to do?"

"Put your robe on, go downstairs and get Frau Blucher--" A horse whiny rang out. "-- and only Frau Blucher." Yet another whinny. "She may know what to do." Frederick instructed, breathing heavily. "I trust her more than I trust Igor."

Inga nodded and slid lightly out of bed, trying to move as little as possible. "But Frederick," Inga paused, her brow wrinkling in confusion, "vere you not de Dean of Anatomy at dat school of medicine in America?"

"The back never was my specialty!" Frederick said hotly, "It was always and only the brain!"

"Okay..." Inga pulled on one of her more concealing robes and glided towards the bedroom door, glancing back at her husband worriedly. She was simply a laboratory assistant; she knew nothing in detail about the human body. She'd never felt more hopeless!

There was a pregnant pause.

"Inga?" Frederick said, sounding thoroughly ill at ease.

"Yes, Doctor?" she asked.

"Could you... assist me by helping me get some clothes on? I don't want... You Know Who to come up and see me like this." Totally naked except for his socks and some blankets covering him.

Inga's face cleared, and she couldn't help but smile slightly. "Oh ya... ya. Yes, of course."

Aw, poor Freddie, don't you think? Well, serves him right. He thought he could bring a dead guy back to life and get away with it! This is karma getting back at him! Ha!

No, I don't really hate him though (He's my favourite character, and Roger Bart is my secret boyfriend. Shhh! ;), but... the reason for his injury is quite funny, non?

Reviews are wonderful!
