The Turtles run an assassin service because well... they're assassins. Not your Nick or Fred Wolf cartoon Turtles. :)
"What did you do today, Donny?" Raphael ended his question with a sai in the middle of a lopsided dart board and shoved a worn beanie bag under his shell. "I shut up this business tycoon who was ripping off some old folks home. The head lady offered me a whole day on Coney Island by ourselves. Don't know how the hell she plans on doing that, but hey, whatever..." He slurped on a two day old can of Coke laying next to him. By the time the television burned signal and a gorgeous thirty-something lady's voice spilled her condolences over the death of some big shot, Raphael grinned through a mouth full of stale Coke and finally looked over his shoulder, wondering why his punctual brother hadn't answered.
Almost on cue, a great boom shook the can in his hand, spilling one drop on his leg and sliding it down his dirty kneecap, and he heard his brother's exploding voice before he saw him. "I take one - FREAKING - job after a hiatus, and it's not an easy one. Noooo, let's give ol' Donnie Boy a FUN one!" A pair of goggles zipped across the room, landing right on the coffee table next to Raphael. "Why didn't you take the Tennis Balls one, Raph? I'm not one for the extramarital affairs and dumb blondes squealing over American Idol. How in the world did -" His eyes sizzled at the back of Raphael's laughing head. "Oh, you were the one who assigned the duties this time?" He fell into sarcasm mode quickly. "Look, pumpkin. You spilled soda all over the tv. I hope you learned how to repair electronics while you were trapped in that pedo's basement."
Raphael licked his lips and took a deep breath. "Did you really chase a tennis coach to a mobster's house and destroy part of it?" His laughter was so loud, it rattled the sai in the dart board.
Donatello stood with one hand on the couch and another on his hip. He watched Raphael's spectacle with as much excitement as an anal evacuation. "There was a slight wrench in the plans, yes. I take full responsibility in not slicing his groin sooner. I didn't count on the blonde being there."
"I got your back, bro," Raphael chuckled and signaled with a thumbs up. "Did you have fun?"
"Hell yeah!"
