As a grad student I somehow turned my experiment under the hood into an evacuation of the entire building, by reducing DMSO to DMS and discovering that Dimethyl Sulfide makes a great building emptier, especially since the hood system sucked (or rather did not). Two Nobel winners and a host of professors and students abandoned the building post haste and they made me go back in to look up whether it was dangerous or not (this was before mobile devices). Thankfully it stinks something fierce but is not fatal likes its cousin, Hydrogen Sulfide.

No wonder I decided programming was safer, code might blow up but it doesn't Blow Up. I also worked in the lab with a guy who worked with ether and smoked in the lab.
