The results are in!

Sam and Max are....drumroll... IDENTICAL TWINS!
We got the results of the DNA test back today. We were just assuming they were fraternal this whole past year, since fraternal twins are genetic and my grandmother was a twin. Identical twins, on the other hand, are totally random, and the odds are 1 in 3000 apparently. Also, to us they don't look identical. But alas, they are!
It will be interesting to see if they look more or less alike as they get older.
