I feel like it is wrong to call C-F bonds the single strongest bonds in o-chem. It just doesn't sound right considering it is not super difficult to break them in many cases. I mean a Carbon carbon triple would almost certainly be stronger.

Serious Comment:
In 3rd year Chemistry labs, we were playing with some seriously dangerous chemicals, but our unfortunate tutors had it even worse! They were all post-grads. I came in one day to see our male tutor (I can't remember his name, just that he was the only male tutor) looking like he'd just had a bath in blood! All his exposed facial skin and both his hands looked like someone had grated the skin off with a cheese grater!! What's worse is that he had no idea how this had happened. He just woke up that morning with a LOT of missing skin! Also, our female tutors were fat, but I think they were always fat...

Best chemistry joke ever:
"If you're not part of the solution, you're part of the precipitate!"

Teflon can hold the very strong superacid (obviously), but I don’t know if it’s totally chemically indestructible.

Trigger warning: the following contains a story of an animal dying... [skunk]

Still here?

I worked at a pest control company in 1996 and was having trouble with a skunk in my suburban neighborhood. It was eating my cat's food.

I put out a live trap for it, caught it and decided that rather than driving in to work, swapping trucks, driving back to get the skunk and disposing of it at the shop like we usually did, I'd just save time and shoot it with a pellet gun.

Perfect head shot caused the thing to tense up and release its entire arsenal of yellow stink-fluid.

People were coming out of their houses a hundred yards downwind with a look of distaste on their faces. Up close, the smell was staggering. A hundred yards away it had attenuated down to horrifying.

It was winter so digging was difficult, but in the garden, I managed to get it about six inches underground and called it good.

Fast forward to springtime. I came home from college to see my landlord digging skunk skin out of a rototiller. There were skunk pieces ALL OVER the back yard and the smell was back.

As I exited the truck, he asks, "Did you know there was a skunk buried in the garden?"

"Yeah... I buried it there."

"Well... you buried it none too deep!"

The poor guy had noticed that I'd done some gardening and had borrowed a tiller to help me out... then found the skunk. When I say "found" I mean he shredded the now-rotting corpse and blew it all over the yard and himself. I guess it went through the machine several times before he got it turned off :-(

Honorable mention to Dimethylmercury. Spill a couple drops on a gloved hand and die.

Fluoroantimonic acid is a close approximation to Alien acid. I would call it a hyperacid as opposed to a superacid.

This is entirely taken from Derek Lowe, specifically Things I Won't Work With. If you're going to copy all his information, the order it's presented in and some direct quotes, you should credit him or this entire list is blatant plagiarism.
