Mailing perfume domestically.

Yeah, I was keeping it down to stuff I've order for home, since I do a lot of ordering for the lab. (Though generally I handle most of the weird stuff ordering for the lab. Other people can totally navigate the Fisher Scientific Catalog. High power laser diodes, kelp crabs, zipline trolleys, I'm your gal. Though to be fair, there was a substantial crowdsourcing component to the zipline trolley.)

My favorite home incident involved my then-roommate (and we had an apartment at the time) ordering nitric acid and getting a call from the front desk that his package - his package that was liberally wrapped in all kinds of paper products - seemed to be leaking. (Nitric acid. Paper. Tee hee.*) He asked them to place the package in the back lot and request that no one come near it, and manage to sprint up to the building in about five minutes.

...it turned out that someone else's shampoo order had been leaking on the package.

* Okay, maybe I find things like that a little too funny. And maybe I shouldn't have been taunting my nephew (my beloved nephew whom I dote upon okay, mostly whom I tease and harass and present lots of educational opportunities to, but that's generally what I mean by doting, right? Ask any of my students...) about nitrogen triiodide, but then apparently he's now making it as a term project with the approval and supervision of his chemistry instructor, so go alternative highschool!
