Stick it in!

I hereby recommend that everyone get a memory stick. It’s useful and all that, but the real reason is how much fun it is to watch people’s expressions when you plug it into their computer. You pull it out of your pocket, often shaking it to seperate it from the rest, unsheathe it, position yourself behind the computer, wiggle a little around the rim, and push that puppy in firmly, yet not forcing it. The computer gives a little whimper upon successfull insertion.

The computer's owner is left looking like you just took their cat’s temperature in front of them.
