I have never heard someone say "habañero", that's hilarious. I live like 20 miles from the Mexico border though so most people speak at least a little Spanish.
I have a roll of these. My girlfriend at the time bought a couple and proceeded to put them on my toothbrush, several knives, and a bunch of my tools. They're almost never not funny.
Brains are often irrational. I have a deep distrust of the electric can opener; I'm always worried it will bite me or something. I have had this irrational fear since I was very young. I have no experience with anyone being harmed by an electric can opener and I'm unaware of any instances of them causing injuries, ever. I know, rationally, that there's no danger. But fuck that thing.
They make you keep it in one of those cylindrical luggage bags and take it with you when you leave.
