Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.
Incredibly exclusive userbase, less than 100 users ever at any one time.
If I encountered a system that badly designed, I would check to see if it takes non-integer ages and maybe get in that way.
Failing that, there's also unreasonably large numbers and negative numbers.
I'm 65535 years old, and you can't prove otherwise!
Only neanderthal kids will remember.
Why stop there? How about a lil' white hat hacking with SQL injection :)
