I am glad to find this thread. I have also wondered if my kids sense of humor is a family attribute or a GT attribute. DD10 has a great timing when it comes to one liners and sarcasm.

My favorite memory is from her toddler years. She was eating a snack of fruit and cubed cheese. She was making a tower from the cheese and purposely not lining up the cubes well. I observed for a while as she was looking if the tower would fall over and asked what she was doing. Her response was: "Look Mom, it's the Leaning Tower of Cheesa". She must have heard about the leaning tower of Pisa somewhere, but I didn't recall talking about it.
