I came across a very interesting story. A guy did a pregnancy test just for fun and posted the results on Reddit.com as the test was positive. The first commenter told him he should have himself checked for testicular cancer. He was right.
When that pregnancy test came back positive, CappnPoopDeck made a rage comic about it, and posted it to Reddit. The very first response, from a user named goxilo, was this: “If this is true, you should check yourself for testicular cancer. Seriously. Google it.”
