This is a great thread! I've thought of a couple more:

From the principal, after the grade skip to first: "It's apparent he didn't go to kindergarten because he answers questions without raising his hand and sometimes runs and talks in the hallway. But the teachers said they can work on those behaviors." Yes, please do. I would like to see his spirit squashed!

From my sister-in-law: "Well, you can have him do sports so he'll be with kids his age, so he doesn't miss out on friends."

And from the teacher after he cried in school due to making a mistake on his paper: "Is he particularly sensitive?" Apparently she didn't read the report from the private testing we went out of state for!

I am simultaneously relieved and frustrated that everyone else hears the same type of stuff!
