What's the Magic Word?

Mckoy: "Can I have some candy?"
Aunt: "Ok, but you have to say the magic word."

My 5-year old son paused for a moment and let out a soft sigh.
Smiling, he confidently replied.

Mckoy: "Abracadabra!"

Everyone started to laugh...except him.
He just stood there with a surprised look.

Aunt: "Marcus, you have to say the magic word."

In a more distinct voice he immediately replied.

Mckoy: "Abracadabra!!!
Aunt: "No, the other magic word."
Mckoy: "Ahh...Kazaam??!!"

Confused, he relunctantly asked.

Mckoy: "Is there another magic word?"
Aunt: "What word do you say when you're asking for something politely?"

He rolled his eyes then replied.

Mckoy: "Ahhhh....Please?"
Aunt: "That's the magic word!"

He gets his treat and walks away.
Shaking his head while opening his treat, he mumbles to himself.

Mckoy: "Magic word?!!! Magic word ba un?!!! That's not a magic word...."
