"My Dad"

Ben has known his last name for a while now, can't exactly pinpoint when we became aware of this, yet I often quiz him from time to time, just to hear him say it.  Cuz it is damn cute and all.  So the other day, we had this exchange:

Me:  "Ben, what is your last name?"
Ben: "Kullman...what is your last name Daddy?"
Me: "Kullman!"
Ben: "NOOO...that's not your last name!"
Me: "Then what is my last name?"
Ben " MY DAD!"

Any hoo...I thought that was cute.  It's cool when Ben recognizes that Ben, Mommy, Caleb, and Daddy are all Kullmans.  As many people know, I was the last male on the family tree and felt a lot of pressure (from myself, not my Dad) to churn out a few more KULL-MEN to get the name back into heavy rotation.
