The next day, the four mutant turtle brothers leapt from rooftop to rooftop in the dark hours of the night, staying true to their nature and keeping hidden to the shadows. Leonardo took the lead, as usual, in their patrol, whilst Raphael stayed at the rear, leaving Donatello and Michelangelo in the middle.

As entertaining as jumping over rooftops was, the youngest turtle, Michelangelo, thought that there was only one small factor that kept this night upbeat and lively.

Silence.

Complete.

And utter.

Silence.

Of course, being born and raised as ninjas, it was in their very nature to be silent. But after the fun filled day they had experienced with each other, the silence seemed to slowly kill whatever happiness or cheerfulness he had beforehand.

Michelangelo Hamato would have none of that.

So it was as they landed on a rooftop, Mikey let out a small smirk. Leonardo instantly heard it and slid his eye behind him. "Mikey..." Leo said slowly, "what're you planning?"

Mikey rocked back and forth on his heels innocently, "Oh nothing, big brother of mine. I was just thinking – "

"Then don't!" Raph snapped, slapping him upside the head.

Mikey let out a cry as he rubbed his aching head, "Dude, I can't stand it anymore! I know we're ninjas and junk, but can't we just have a little fun? Please?!" he begged.

Leo let out a sigh and placed a hand on Mikey's shoulder, "Maybe later, Mikey. Right now, we have mutagen canisters to find," his gaze wandered to Raph and Donnie, "let's keep moving, guys," he said as he leapt off the roof, followed by Raph, Donnie and a downcast Mikey.

As they ran through the night, Leo could not help bust cast a glance to Mikey behind him. It killed him to see the always cheerful turtle like that…

With a quiet sigh, he did the one thing he never thought he would do.

He began to whistle the opening tune to the Irish Drinking Song.

The other three immediately noticed, and began to snigger. "Dude, I knew you wanted it!" Mikey laughed.

Leo smiled, "Okay, but we have to keep it down…" he said, and with that, as they continued to run through the night, the Irish Drinking Song commenced…

All: Oh, Idey, idey, idey, idey, idey, idey I!

Donnie: I took April on a date,

Raph: (let out a bark of laughter) We went out for the night,

Leo: As we hit the parking lot,

Mikey: I got into a fight!

Donnie:…then he took my Bo staff,

Raph: And ran away so fast,

Leo: Donnie started crying

Mikey:…and a stoner I passed!

All: (snickering) Oh, Idey, idey, idey, idey, idey, idey I!

Raph: I screamed just like a lassie!

Leo: What he did was wrong,

Mikey: I jumped into my car,

Donnie: The mugger's name was thong – I mean, Fong!

Raph: (laughing hard) I put upon my siren,

Leo: It made me want to hurl,

Mikey: (giggling) He came to a stop,

Donnie: And beat me in front my girl!

All: (The four turtles nearly tripped over the roof as they started laughing, though they tried to keep it as silent as they could by covering their mouths with their hands. They settled their laughter and continued.)

Leo: I decided to fight back,

Mikey: I hit him with a club!

Donnie: I hit him where the sun don't shine,

Raph: He said, "HEY, WATCH IT, BUB!"

Leo: (shushing Raph whilst trying to force back his own laughter) Then he ran away from me,

Mikey: He ran very fast!

Donnie: I became a hero,

Raph: Because I kicked his ass!

All: (laughing a little louder than they should have) Oh, Idey, idey, idey, idey, idey, idey I!

Mikey: I still hear from,

Donnie: From…often!

Raph: He writes a little letter,

Leo:…It's as soft as cotton!

Mikey: (snorting) And someday I'll write back!

Donnie: He is my best friend!

Raph: And now we both are pen pals,

Leo: He put my stone back in my end!

All: (apart from Donnie and Raph, who had now dropped laughing on the roof they landed on and were writhing in laughter) Oh, Idey, idey, idey, idey, idey, idey I! Oh I! Daye! Daye! Dee! Daaayyyyyeeeee!

As they finished, Leo and Mikey joined their brothers on the floor as they all laughed harder than they had that day.

"H-he put my stone back in m-my – ahahahahaha!" Donnie hollered breathlessly, "What was that?!"

"N-now that is a good friend!" Raph chortled.

"Best…patrol…ever!" Mikey breathed as they finally calmed down enough to get back on their feet again.

"The worst thing about that was that it was apparently Fong who was my best friend," Leo chuckled, "Donnie, why Fong?"

Donnie shrugged with a grin, "I dunno, I just –"

"Hey! It's those turtle freaks!"

The turtles looked down sharply to see The Purple Dragons glaring up at them as they began to climb the fire escape, drawing their knives as they raced to catch them.

Leo slid a glance at Mikey. Mikey rubbed the back of his head shyly. "Um…my bad," he laughed nervously.

However, Leo began to grin. "Hey, Mikey. Do you have a stone I could borrow or something?"

The other three shared a confused glance. "Why?"

Leo's eyes gleamed mischievously, "I'm gonna put my friend's stone back in his end."

By the end of the scuffle, The Purple Dragons lay at the bottom of the building, groaning in pain whilst the police came and arrested them, wondering why one of the goons looked as if a stone had been brutally kicked up his behind.

A/N: Lol, poor Fong! Yes, this is also based of an original drinking song from the show, lol I'm really running out of ideas. I hope you liked it!
