#47 you obviously haven't heard of accents before then??
Both merry-oh and mah-ree-oh are correct in their own rights. They are the way it's said in both dialects of English (American and British).
If you want to be 100% correct you would use a real Italian accent, not the fake accent the voice actor Charles Martinet uses.

It's actually more like the name "Maria" is pronounced, being that Mario is the Masculine of it. Phonetically pronounced "Muh-Rio"
Muh as in 'Mud'
Rio as in 'Rio' Grande, Rio de Janero, etc

You are just a dick about it mate and ANY pronunciation different than your own is wrong. Let me guess.... You're American??
