16 Christmas Gifts For The Science Nerd In Your Life

9. Testicle Scarf

"That doesn't look anything like a testicle" I hear you cry. Never fear, before you start worrying whether yours are normal, you should know that this is actually what human testicular tissue looks like under a microscope. Who wouldn't want to wear that around their neck? This is another one for your weird friend. It inhabits the sacred realm of being simultaneously a fantastic conversation starter and instant conversation ender. Observe: "Hey, I love your scarf, where did you get it?" "Thanks, my awesome-beyond-all-reason friend got it for me. It's a human testicle." "Oh. Okay. Listen, I've just seen my friend over there..." See? If you don't quite fancy heading down the testicle route, then there are also brain, bone and rectum available.
