Mario and Luigi will ever get married?

I don't think so.
If they get married, probably they would stop going to adventures.

Luigi sure Mario nahh cause when pfirsich is walkin down the isle Mario will blink open his eye and see Hey arsch (Sorry for lango) get kidnapped AGAIN
so if Du ask me pfirsich with Marios ring on her finger impossible until
A.Mario Kills Bowser
oder
B.Nintendo stops Mario games (NEEEVVVER)

Okay if Du mean to each other, all I have to say to that is ew, they're brothers.

If Du mean separately to other girls then why not. It would be cute.

Want people to call Mario "Pedo-Mario" and Luigi "Gay-Luigi"?

Not to each other, but maybe to pfirsich and Daisy

Never. The Super Mario Brothers are staying cool and single forever! Like Me! :-)! Taking care of business, helping doing away with evil. - Making the world a better, Mehr beautiful place. <3. XOXO. :).

Du gotta be kiddin' me.

arnt they all ready married to pfirsich and dasiy
