In between takes, on set for White House Down, Channing decided to work on his now not-so-secret handshake with his daughter-on-set Joey King.
Apparently they had walkie-talkies in order to coordinate practice periods between scenes.
Thirty seconds long and really impressive, ladies and gents, I present to you the "Channshake"!
It's small moments like these that give a "plus ten" on the daddy score board.
White House Down comes out in theatres on June 28, 2013.
