Coming from a country that loves Pie and Cake (Germany), but puts more emphasis on Cake because we German's have a real sweet tooth. Let me put it like this:
1. Like Master L said, pizza is a kind of pie, the variety of pie is enough to appease the pickiest of people. The variety of pizza, too.
2. Cake is awesome, chocolate cake, Oreo cake, Black forest cherry cake, Marzipan cake, cream cake, cake, cake, cake.
3. I've made my decision: to defy this trend and accept both EQUALLY into my diet. I need to gain weight anyways.
