Why Yao Ming and I are twins separated at birth:

1.) We are both Chinese
2.) We are both 22 years old.
3.) We both can't live without Chinese food
4.) He's 7'5", I'm 5'7" (actually, closer to 5'8", but you get the idea)
5.) We are both stand-up comedians with hordes of fans
6.) We are both well-hung. Well, I don't know about him but it's easy to make the assumption.
7.) We both have game, in more than one way.
8.) He was in an Apple commercial, I majored in CS.

I'll continually update this comparison as more things come to mind.
