unusual dialog for matching players in tapball game

Good glayvin! Our tap ball team just faced off against alternate versions of themselves!
But they were wearing red and black instead of blue and white, so they're evil.
How does that make them evil?
There's a history of such things in games.
It's-a me, Waluigi! We're-a gonna win!
Too late, Waluigi. The game's over. Your team already went home.
Oh, that's-a not a spicy meatball.
Okay, well... it was-a me, Waluigi. I'm-a gonna go.
