I prefer pie to cake. Don't you? Cake is cake, but pie is pie, and well pie is better than cake.
Hookers are better than pie, which means that hookers are better than cake as well -- but not always. Some of the time pie is better than hookers, but usually not cake, so pie can be better than hookers, but never cake.
It's refreshing to have constants in ones life.
Pie will always be better than cake, and sometimes it's better than hookers.
