Last Name, please?

This is from Tuesday night. Colter managed to lose most of this set of letters before we left Minneapolis, but still loves to play with them anyway. He did figure out there were just enough letters to spell something, however. Neither Jenn nor I did anything to coach him on this. Jenn was washing dishes at the time and I was sitting at the table when he said out loud, "H, Woo, B, E, R. Colter Hoober." I quickly grabbed the camera before he mixed them all up again.
