lose those thumbs!
Random conversation while watching E.R., they're treating a chimp, and they just said 96% of human and chimp DNA is similar
"Is that true?"
"Yeah, that sounds right."
"So what makes us so special or different?"
"I don't know... opposable thumbs"
"What? Disposable thumbs?"
Me (heavily sarcastic)
"Yes, disposable thumbs. I toss mine out all the time when i get bored or tired of them."
