Fun with Daddy

The buddies spent a lot of time with just Daddy last weekend since I spent Saturday morning at my cooking club and Saturday evening with friends at a movie. They learn some unusual things from their dad. Here's what Steve and the buddies proudly showed me when I returned:

Steve: How does the train go?
Buddies: Choo-choo (pumping arms)

Steve: How does a car go?
Buddies: Beep-beep! (arms out front as if honking horns)

Steve: How does Brian Westbrook go?
Buddies: Ta-da! translation: touchdown! (arms held high above heads)

Steve: How does Reggie Brown go?
Buddies: Silent but waving arms in the sign for first down.

Can anyone guess which lessons they learned from their dad and which from me? Hmmm...
