From Harry Potter wiki: "The Summoning Charm (Accio) was a charm that caused an object at a distance from the caster to fly into their arms."
  1. When I'm on my couch working (ListApping) and my computer charger is across the room.
  2. Anytime I've been hungover.
  3. When you realize too late that there's no TP in a public bathroom.
  4. After I walk into a room for the express purpose of grabbing one thing, forget what it was I meant to get, go back to whatever room I was in, and immediately remember what I wanted.
  5. When I've walked out the door without my keys/wallet/phone.
  6. When there're no condoms immediately available.
  7. The next time I'm head to head with a nasty Hungarian Horntail and I need my trusty Firebolt.
  8. Now that I'm thinking about it, though, you could steal SO MUCH SHIT.
    But I'd probably just stick to candy. "With great power..." and all that.
  9. In a fight
    Accio Appendix! I never understood why they didn't use it more in duels.
