So, my teenager asks me this question yesterday…
“Hey, Dad. What did the Zero say to the Eight?”
“Um…. no idea. What.”
“….. (grinning)…. Nice belt.”
I also recommend NOT asking this of your own school-aged kids. They probably already know it, and then you will have proven that you are a lame parent.
“Duh, dad… ‘Nice Belt’. That was totally on a milk-carton at school.”
