Did Dad invent the game handball?

Taylor and the boys are playing handball against the wall in the playroom.

I hear Taylor and Nolan arguing over the "rules".

Taylor- "Nolan I think I know the rules of handball. I made the game up. Ask your mom."

Nolan (yelling from downstairs)- "MOM!? DID DAD INVENT HANDBALL?"

Me (playing along from the kitchen)- "Uh huh... yes he did."

Nolan- "Yeah right! I am going to have to look that up on the computer."

Darn you google. How are we supposed to tease our kids?!
