Awhile back, I was on a science expedition to the outer galaxy when suddenly, I and my team were hit with cosmic rays. We didn't feel any immediate effects, but when we returned to Earth, we felt....different. My body became like elastic. Sue and Johnny were affected in unique ways as well. Sue could turn invisible and Johnny became a human torch who could fly. I am certain the same cosmic rays also hit the Earth and began to change humans, too....with even weirder results. Now, not all males are men and not all females are women. Vaginas are now penises and penises are now vaginas. Children can now make adult decisions and adults can now act like irresponsible children. It's like Bizarro Earth, now. Even a former Olympic Decathlon gold medalist who was once considered a man among men, has now been rendered into a feminine politician...not to mention the whole Donald Trump as POTUS deal...
Cosmic rays.
