One of Sam’s teachers told me that he was the class clown. (When my wife was told the same thing at a parent-teacher conference, she said it must be genetic.)
Sounded possibly like a bad review of his behavior, but the teacher assured me that it wasn’t, that he just says things that make even his teachers laugh. And apparently at a much greater rate than most 3 year olds.
He also knows how to play straight man for his twin brother. Both of them at times like to speak in lists. Here’s a recent example:
Sam: I love Mommy, I love Daddy, I love Sammy, I love Jack.
(I looked over at his brother, to see if had anything to add. After a short pause…)
Jack: I love breakfast tacos.
