Cuphead runs around in a circle and Game Djimmi appears in front of him.
Djimmi: Cuphead, I grant you three wishes. You can't ask to bring someone dead back to life, to kill someone, or find a random person to become your new best friend aside from Mugman and Chalice.
Cuphead: I wish for you to have no wishes left.
Djimmi: Your wish is my command! Now, you have 255 wishes!
Did you get the joke here?
So what exactly is an integer overflow?
Think of the mile counter on the odometer of your vehicle. They have a min value of 0 and a max of 99999. What if you drove one more mile? Of course, the counter would reset back to zero, or even make the car go backwards to roll back the odometer.
What are examples of integer overflow?
Gangnam Style's view count above 2,147,483,647. YT needed to upgrade to 64-bit to prevent it.
The Tree of Wisdom from Plants vs. Zombies. After reaching the max height of 2,147,483,647 feet, it will go back to a sapling and needs to be fed 2,147,483,647 times before its height goes back to zero.
A famous example of this is Y2K, where years were named by their last two digits. For example, 1936 would be "36". On January 1, 2000, computer clocks will reset the year date to "00", making 2000 indistinguishable from 1900.
