OoOoOoO
Sasuke's eyelids were heavy, and his ears were ringing. He couldn't do anything but listen – they wouldn't let him go, no matter how many times he tried...
"Oh, I have another one! Why do scientists call helium, curium, and barium the medical elements?"
"Easy. If you can't helium or curium, you barium!"
Laughter resonated through the nearly-empty dining room.
"What's the fastest way to determine the gender of a chromosome?"
"Pull down it's genes?"
"Yep!"
There was another pause and more giggling commenced.
"Hey, did you hear about the famous microbiologist who traveled in thirty countries and learned to speak six languages? He was a man of many cultures!"
"Pffft...ahahahahaha!"
Sasuke buried his head in his hands. When the hell would this torture end?
"Two hydrogen atoms walk into a bar. One says, "I think I've lost an electron". The other asks, "are you sure?" The first one says, "I'm positive"!"
Orochimaru burst into another fit of cackles, tears forming in the corners his snake-like eyes, and Kabuto pushed his glasses further up the bridge of his nose while choking on his laughter. The snake sannin calmed down, but his cheery attitude remained.
"I have a song...Saki was in chemistry, Saki is no more – what she thought was H2O was H2SO4!"
The two missing-nin began to guffaw, snort, and snicker once again. Sasuke smashed a water glass against the back of his head in an attempt to knock himself out. It didn't work in the slightest.
"What do you call a joke that's based on cobalt, radon, and yttrium?"
"Co-Rn-Y!"
Sasuke would never bring up the subject of jokes at dinner ever again.
OoOoOoO
What do you get when you cross a FanFiction writer, the internet, and fairy dust?
Cracktastic nonsense, that's what!
This is what happens when I search science jokes on Google.
And since Kabuto and Orochimaru deal with science-ey stuff, I found the jokes fitting for the two.
