Cheeseburg is the city where Adolf Hitler invented the cheeseburger. It is located directly below Mecklenburg and above Kassel. Though some foolish Germans insist on calling Cheeseburg Kaseburg, they are merely ignorant people who will be deported to France as soon as humanly possible.
Cheeseburg and its cheeseburger are actually older than Hamburg and its hamburger, though some would claim otherwise. This can be proven by subtracting e=mc^2 from the sum of the amount of pirate boots and the number of Chinese people currently in Thailand.
