First of all, the best bite of pizza is not the tip, but the saucy bit right next to the crust. Even assuming that the tip would be the best part, it is the part of the pizza that cools off the fastest, and pizza is best served warm, so it makes the most sense to start off from the part that cools off first for maximum deliciousness. Not only that, but by eating the crust last, you are less likely to get messy fingers because things get really awkward when you try eating pizza according to the Remarkable Theorem, which is unmistakably the only right way to eat slices of pizza.
Your weekend analogy is also very flawed. Perhaps you've been taught that Sunday is the first day of the week in whatever ass-backwards place you come from, but in most of the world, and according to the International Organization for Standardization, the first day of the week is Monday. Sunday is literally part of the weekend, which I agree is the best part of the week.
Time to face the facts, Bosman: your way of eating pizza is disturbing, it's disgusting, and it's just plain wrong. I hope you take some time to think about this, and ultimately admit to yourself that there is only one correct way to eat pizza: crust last.
Fallacies are what i read here.
To start with, everybody knows that Sunday is a depressing day (unless it's Footbal season) because you know what follows is a Monday, the very worst day, Fridays and Saturdays are the best.
You are right, the very end of the pizza before the crust is where the topping magic is, that's why you is crazy to eat it for last, you basically are left with two options, you eat the top and all is left is the boring and almost tasteless crust as a final bite, or you eat the top part alongide the crust, therefore killing the magic that is in the top by also consuming the crust.
Reverse the pizza slice, eat the crust first, re-reverse the pizza to eat bottom to top and the world will be a better place.
