A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

This is a science community. We use the Dawkins definition of meme.

Mammals have a lot of weird dick things. Some bats have gone from penetrative sex back to just like touching genitals because their dicks are so huge they literally don't fit anymore.
