They say, 'while the cats away, the mice will play.'  Apparently the same thing goes, when mom's away.  Check out this time lapse video of dad playing with his kid, while mom is at work.   There's lots of playing, high fives and messes.  At one point, both baby and dad are even shirtless.  All that playing must have made them hot.  But being the good husband he is, its all cleaned up by the time mom gets home.  What a guy!
