Game: "carry the baby"

I see mamas in poor countries walking up and down the streets between cars selling oranges, cigarettes, gum, candy with their babies strapped to their backs.  Here's a game to show how difficult that can be.

6 cardboard boxes (big enough to be lifted by one person usign both hands) are arranged in a given configuration.  Plyers take turns.  The aim is for the player to move the entire display 2 meters over by dismantling the installation and moving it over box by box as fast as possible while carrying a raw egg.  The winner is whoever completes the game in the shortest time.

Notes on the egg: this egg represents the player's baby and cannot be broken, dropped or placed on the ground.
