Okay, someone who _isn't_ Lola Prue might have something to say... :) Anyway, exactly who Mario's parents are is a matter of some debate. According to ancient history way back in the eighties, Mario and Luigi are plumbers in Brooklyn, New York, who travel down the wrong pipe and end up in the Mushroom Kingdom. We could probably assume that the bros.' parents are two good Italian folks from that area. According to the ending of Yoshi's Island, however, the stork delivers the twins Mario and Luigi to their parents in the Mushroom Kingdom. It's actually a very charming scene, but all we see of Mr. and Mrs. Mario is their feet and the bottom of their nightgowns. So there you have it.
