I'm a plumber and i'm okay.
A monty python song.

Mario is battling Bowser.

Bowser : Your finished now sewer scum!

Mario : Mama-mia! I never wanted to do this job! I wanted to be..a...a... A PLUMBER!
*piano vamp*

Mario : Leaping from pipe to pipe! as they float down the mighty river of British Columbia!
With my best buddy at my side! The u-bend! The straight! The giant bathtub drain! The sink! The loo! We'd sing! Sing! Sing!

*singing* Oh, i'm a plumber and i'm okay. I sleep all night and I work all day.

Chorus Goombas : He's a plumber and he's okay, he sleeps all night and he works all day.

Mario : I cut open pipes, I eat my lunch. I go to the lava-try. On wensdays I go shoppin'. And I have buttered scones for tea.

Koopa Mounties : He cuts open pipes, he eats his lunch. He goes to the lava-try. On wensdays e' goes shoppin' and has buttered scones for tea.

Mario : I skip and jump, I like to press wild flowers, wear women's clothing and I hang around in bars.

Koopa Mounties : He skips and jumps, he likes to press wild flowers, he wears women's clothing.... and hangs around in...... BARS???????? *They look at each  other puzzled*

Mario : I wear high heels, suspenders and a bra. I wish i'd been a girlie like my dear mama.

Koopa Mounties : He wears high heels.... suspenders and a bra? Wants to be a GIRLIE? And we thought you were so rugged! Poofter!

Chorus Goombas : He's a plumber and he's OOOOOOOOOOOOOOOOOKAY!
