Pictures of Identical Twins

Usually the first question strangers ask me is, "Twins? Are the identical?". My answer is yes and yes.  It makes me feel like such an idiot when people then say, "They arrrrrrre? Are you sure? They don't look it." I don't care if they are or aren't, but it's annoying to argue something that they asked in the first place. I always have to explain that there was one placenta and one sack (chorion) with a thin membrane dividing the two babes. And while this is the most common type of identical twins, I suppose there is a small chance that the placenta fused and blah blah blah. In short: The only way to know for sure is to take a DNA test.
I'm sort of tempted to get one. Or perhaps a photoshopped official looking DNA Identical Twin certificate will do. Shrunken down to fit in my wallet. And laminated! That would save me $160 dollars and give me the last word every time. "Look here, it's an official DNA test certificate! Proof!" Nope, that won't work. I feel like an idiot for even thinking of that idea.
Here's the pictures I took today. I wanted to put them side by side for comparison. They do look different, I know. But I promise they're identical. If Owen would stop scowling for one second, I could prove it. Maybe I should just say fraternal and be done with it. But, secretly, I think it's cooler if they are identical. Maybe I do care. Someone draft up a certificate stat!
What about you? Do you have twins? Are people always arguing what type they are?
