I was giving the boys a bath last night and they have this phrase/gesture combination where they yell 'Ta-Da!' and open their arms out wide. Not sure where it came from (think the Croods sloth). They were in the tub alternating 'Ta-Da!' yells, and opening their arms. Of course in the tub this resulted in water going everywhere and boys accidentally hitting each other with the arms gesture. So I say "Hey guys, that's it, no more 'Ta-Da!' in the tub!". Michael looks me in the eyes and does the arm gesture and yells 'La-La!". I busted out laughing - parental authority lost in the situation. Technically he did not do the 'Ta-Da!', by switching it up to 'La-La!', the kid won this round on a technicality resulting in huge laughter from all three of us.
