Hilarious "Darwin Fish" Shirts
I stumbled upon this little shop today, and ended up spending over $50 on shirts and stickers for my brother and two cousins, all of whom are biologists and/or geneticists.  The simplicity of the design really intrigued me, and I think it'll definitely serve my family well at their jobs!  Anyway, I thought you guys might at least appreciate it if you don't buy anything.
