You've got a point there... Wario's past does sound a little strange. Imean, Wario has a yellow hat and purple overalls, right? And his hat has a W on it, sorta like the M on Mario's hat only upside down. And Wario has a crooked mousetach, while Mario's is like a funny looking smile... If you ask me... I think Wario is an alien who was raised by Mario's parents while they were little. That explains why Mario calls him his "twin" or "cousin"...
