Mandatory military service
Used to be a thing for people who were born in the 80s (me)
So I'm 18, had to sign up for recruit and spend the day making physical and mental tests. I made sure to sabotage every test so my results would match a individual with single iq digits.
At the end, the military officer was looking at my results and asked if I wanted to be in the military, to which I replied swiftly "absolutely not"
He said without looking at me, "good, you're in"
WTF
