Underflow Memes

Classic unsigned 8-bit integer overflow hack! The genie says "3 wishes left" but our clever programmer wishes for "0 wishes left" causing the counter to underflow from 0 to 255. It's the digital equivalent of rolling your car's odometer backward, except you're exploiting the genie's primitive variable type implementation instead of committing odometer fraud. Somewhere, a CS professor is using this as an example of why input validation matters.
