A day without Mozart is like a day without marzipan
Ooh, where's that ten foot pole that I don't touch things with now that I really need it?
In a related story, the Florida Orange Juice Council used to have an ad slogan, "Breakfast without orange juice is like a day without sunshine".  Sometime later, to increase the sales of their product they got a new slogan, "Orange, juice; it's not just for breakfast any more".  This prompted me to recast their older slogan, "Orange juice without breakfast is like sunshine without a day".
