Hey! RoxyGoth here! My brain gave me this idea, because lots of people are talking about Donnie's relationship with Splinter. So I decided to make my own fic.

I do not own TMNT in any way shape or form.

As Donnie strolled into the room with his hands behind his back, Raph nudged Leo. "Look out, here comes Jimmy Neutron."

Don rolled his eyes before grinning and whispering. "Hey check out what I made." He held out a small cube with little buttons on it.

Leo looked at it and said. "The destroyer of the universe?"

From the end of the sofa Mikey giggled into his shoulder and Don shot him an ice-glare before saying. "NO. It's a new style of TV control. You simply pick the channel you want via one of the buttons and voila! The show instantly changes over! Isn't it neat?"

"So you've basically invented…the TV Remote?" Leo said, slowly.

As their brothers left eyebrow twitched, Mikey chimed in with. "Yeah, I think someone already beat you to that, bro! Hey, maybe next time-"

"IT IS NOT A TV CONTROL!" Donnie snapped and they all froze, expecting to scold them for distracting his shows. When he didn't move, they all sighed a sigh of relief and Purple carried on. "Well it is, but it isn't. It's an ultimate TV control, you can access any TV show at any time."

"Oh, neat! Let's give it a go then-" Mikey reached his hand out only to have it swatted away by his older brother.

"No, Michael! It's for Pops."

Those three words sent a sense of foreboding down each of Purple's brothers shells and they looked at each other, before Raph said hesitatingly. "You sure that's a good idea, Don?"

His immediate younger brother waved a hand dismissively. "It'll be fine. And he'll actually understand this one, because, hello? It's telly, what's not to love? I'm gonna go give it to him now."

"Good luck." Leo said, as Donnie bounded off. "You're gonna need it." He muttered under his breath.

The teen genius cleared his throat as he slid up to his father chair. "Oh, papa?"

"Not now Purple! I'm watching TV."

They saw Donnie's shoulders tense and then de-tense as he stepped expertly in front of the screen.

Mikey buried his head in his hands. "I can't look."

"I have an invention for you!" Donnie held it out straight under Splinters nose. "It's the ultimate TV remote!"

That caught Splinters attention. "Ultimate TV remote?"

Purple took that as encouragement and perched on the arm of his pops chair. "Yeah! So it's made off-" And went into an explanation that no one aside from maybe Stephen Hawking would understand.

Even from behind the other three could tell Splinter wasn't listening, so how Donnie could miss the obvious signs when he was sitting practically nose to nose from him is anyone's guess.

Mikey looked up. "Is it working?"

"He hasn't dismissed him immediately." Raph said optimistally.

"Yeah, but he's not listening either." Leo said, sitting forward and watching the scene intently. "And that's gonna cause issues when Donnie says-"

"So what do you think?"

"That." Leo leaned back in his chair and folded his arms, still watching intently.

There was a pause, then Splinter said. "So it is a TV remote?"

Don face-palmed and said, with remarkable patience. "It's the ULTIMATE TV remote, Pops. Way better than the one we've got at the moment because you can get ALL – and I do mean ALL – the channels on it!"

There was another pause while Splinter digested this, and the other three waited with baited breath, wondering if this would finally be the invention that cracked Splinters harsh exterior.

"…But what is the point when you only have one screen?"

The other three couldn't help letting out simultaneous groans at that, Leo even going so far as to grab a cushion and throw it over his own face.

Donnie blinked "Sorry what?"

"There is only one screen, so how am I meant to watch more shows?"

Another agonising pause then Don said, with a certain level of ice underlying the words. "You're not meant to be able to watch more than one show at one time. You're meant to be able to switch shows faster. It's inspired by the upgrades to Sky."

"They've made upgrades to the sky!?" Splinter said looking up.

Normally Donnie would face-palm at this point before trying fructuously to explain his genius. This time however he just looked at Splinter and said. "You don't get it do you? You really don't get it?"

Raph, Leo and Mikey all looked at each other with probably about the same amount of confusion that the old rat was feeling now. "Sorry, Purple?"

That did it. "DONATELLO! My name is DONATELLO!" Said turtle screamed, bouncing of the chair at rocket speed. "And they're RAPHAEL, LEONARDO and MICHAELANGELO!"

Splinter blinked. "I know who they-"

"WELL CALL US BY OUR NAMES THEN!"

"Donatello, I will not have you speaking to me in this disrespectful manner!"

All three brothers face-palmed as Donnie's face went the same shade as his mask. "Oh! So we can't disrespect you but it's alright for you to be rude about the many, MANY inventions I spend HOURS –DAYS-WEEKS even making for YOU!? Do you know how long that took me!?" He pointed at arm at the Ultimate Remote, hanging perilously onto the armchair. "EIGHT weeks. And you can't even be bothered to look at it properly or even sound VAGUELLY interested when I explain it to you! And you're doing it now, looking at me like you don't have a clue what I'm talking about! Well, I'm done." And he turned and bolted out the door at lightning speed, slamming it behind him.

The remote finally fell as all four occupants of the room stared after him.
