What Not to Say to Biracial Person

I'm not gonna get preachy, but there are a few things one should think twice about before saying them to a mixed a person:
"Mixed babies are so cute." We're not pandas and therefore we're not uniformly adorable. I mean, have you seen Malcolm Gladwell's hair?! (Nothing against MG; his brain makes up for the bad 'fro)
"My cousin married a (insert minority here) and their kids are mixed." This is second only to "I love gay people...my best friend is gay" when it comes to statements that don't prove you're open minded.
"Which parent is which?" Why is this interesting? And what will the children of my friends Natalie and Greg say to this question considering both Natalie and Greg are hapa?
"You aren't really (insert minority here)." Really? What am I? I'd love for you to tell me more about myself.
"People don't know you're (insert minority here)." Yes, they do. How do I know they don't think I'm white? Because you JUST asked me, "What are you?"

You get the idea. If you would be surprised if I said it to you, about you, please don't say it to me (even if you mean it in the nicest way.
