Damn, Mario really goes out of the way to make sure not even the bellhops catch him! I suppose he's had lots of experience evading the paparazzi by this point.
And I know what was up with the tuxedo now that I know its for an awards thing. Awards ceremonies are formal, so the bellhop was trying to get Mario to wear a tuxedo intead of his overalls.
I found it funny how at the end, Mario was all like "Yoohoo! Over here, you scootcha alamenz!"
That means 'pain in the butt' in Italian, but I have no clue how to spell it. I just know say it. "Sckoo-che al-ah-menz".
Easy. Mario needs his tuxedo, but he assumes that he's being chased because he's famous, and the bellhop wants his autograph or something. I think... Maybe he just really likes overalls.
