I saved my personal favorite for last...
"Have a fine rest."
"I am a very strong man, and a very smart man too."
"Get the bug smacker Mommy, I see a bug!
"Did you see me playing with those kids at the park? It was amazing!"
The tail end of a discussion in the car I said, "If you were doing as I asked then you wouldn't know that the windows were locked." To which he replied, "Yes, I would still know ... ... ... ... ... ... ... because I have a brain."
