A/N: Today is Minerva McGonagall's birthday, and I wanted to celebrate it. :) So here is a little fic for you. Oh, if you see three dots in a row (…) it means that the word is being dragged out at the end. Enjoy!

Happy Birthday!

Harry walked along the Transfiguration corridor silently. He was lost in thought. But when he passed by the Transfiguration classroom, he was pulled from his thoughts at the sound of his mentor's voice.

"Come now my dear. Tell me what you want for you Birthday tomorrow."

Intrigued, he stepped up beside the door to the classroom and looked through the gap. Inside was his Head of House and the Headmaster. His Professor looked irritated at the interruption of her marking, while Dumbledore seemed as though he didn't notice.

"For the last time Albus, I don't want anything for my Birthday! Now can you please leave me alone." Came the sharp reply of the Deputy Headmistress.

Harry slowly backed away from the door as the Headmaster stood up from his seat in front of Professor McGonagall's desk.

"Of course my dear."

As quietly as he could, Harry ran down the rest of the hallway and up to Gryffindor tower. He had to speak to the twins.

The next morning, Harry walked into the Great Hall nervously. Last night he had told the twins what he had overheard, and straight away they had started throwing ideas around. Finally at eleven o'clock, they agreed on a plan and set everything up for the next day.

He looked around the Great Hall quickly, nearly everyone was there. Nodding to himself, he walked back outside and up to the twins.

"Well?" They asked in unison.

"It's now or never."

The two red heads smiled at Harry and nodded their heads.

All together they walked up to the closed doors of the Great Hall and paused as they put in their mouth pieces.

Taking a deep breath, Harry nodded to the pair behind him. They quickly waved their wands together before putting them away. From inside the hall, the sound of music could be heard faintly.

"Let's do it."

Harry threw open the doors to the Hall and marched inside, speaking deep voice.

This is just a little something,

That I want you to remember,

Because today is a special day,

That I wanted to…

Harry turned to the twins behind him. "What rhymes with Remember?"

The twins looked at each other and shrugged. Harry turned back to face the staff table again and started to sing.

Word is on the street that someone's getting older,

It's not me, or she, or he, I believe it's you dear…

Harry pointed at McGonagall as he sang, smiling.

We're so lucky to be with you,

One more time and you're turning one more year.

It's you!

Yeah it's you!

You're the main attraction today,

It is you!

I sing to you today,

It's your Birthday…

Happy Birthday!

I wish you all the love and happiness in the world,

Lots of wishes come true from your favourite class…

(Twins) US!

Gives you lots of hugs and kisses of so sweet,

You deserve all the best things you can meet…

It's you!

Yeah it's you!

You're the main attraction today,

It is you!

I sing to you today,

It's your Birthday…

Happy Birthday!

It's you!

Today it's you!

You're the main attraction today,

I sing to you today,

Not to you…

Harry pointed to the grinning Headmaster, than looked back to his Head of House.

All I could do,

Was write you this crappy tune,

And sing to you,

I sing to you,

It's your Birthday…

It's your Birthday…

It's your Birthday…

Happy Birthday to you!

To you!

To you!

You!

You!

You!

You!

To you!

To you!

To you!

To you!

Harry took a deep breath so he could hold the final note along with the twins.

Happy Birthday, to you…

He finished, panting. He looked up at the shocked expression of his Head of House and smiled. "Happy Birthday Professor."
