Here's a parody to the song "What Would Brian Boitano Do?" from the South Park movie:
I don't own Yu-Gi-Oh! or South Park!

~What Would Yugi Moto Do?~

(EVERYONE)
What would Yugi Moto Do?
If he were here right now?
He'd make a plan,
And He'd follow through
That's what Yugi Moto'd do!

Whan Yugi Moto was in the Duelist Kingdom
Fighting for the souls
He played two ritual summons
And a Kuriboh
While wearing his puzzle!

When Yugi Moto was on the boat
Talking to Weevil
He jumped over the railing
Into the sea
To save Joey Wheeler!

So what would Yugi Moto do?
If he were here today?
I'm sure he'd kick an ass or two,
That's what Yugi Moto'd do!

(YUGI)
I want this spirit outta me,
It has stuntyed my magical energies!

(RYOU)
And I just want my Yami
To stop banishing everyone!

(JOEY)
For Mai I'll be a great duelist, too
'Cus 'dat's what Yugi Moto'd do!

So what would Yugi Moto do
Get all his friends in town
And tell them to unite for truth
That's what Yugi Moto do!

When Yugi Moto dueled in the finals
For his Grandpa's soul
He fought the evil Pegasus
To free them all again

And when Yami Moto built the pyramids
He locked away the shadow games!
'Cus Yugi Moto dosn't take shit
From Anybody!

So let's call all our friends together,
And unite to stop Peggsy,
And we'll free the Kaiba Brothers too
'Cus that's what Yugi Moto'd do!

And we'll free the Kaiba Brothers too
'Cus that's what Yugi Moto'd do!

'CUS THAT'S WHAT YUGI MOTO'D DO!
