Ka-Chow! It's just fun to say.
I read that the writers asked Owen Wilson to make up a signature line that sounds like a lightening bolt. In retrospect, "Ka-Chow" really is something Wilson would say.
Sooo....I made an appointment for a haircut this weekend but yesterday I had one of my best hair days ever. It's like my hair went "oh sht, better get my act together before she really gets bored and goes for the short cut!" I actually cancelled my appointment.
