In Denmark, we have mandatory military service. At the draft office, they tested us with a whole battery of IQ tests.
Apparently, I did really well, and they told me I had the highest score of that day. That wanted to draft me.
I didn't want to be drafted though, so I put my new IQ score to work figuring out a way to dodge it. Turns out I had some very rare heart condition that took a long time to get proven and diagnosed, but once I had the paper from the doctor, the draft office discarded me. I then got the heart condition treated, and hey presto, a free man.
When I told my brother about that story, he said "I just ticked random boxes in the test and they discarded me, too".
