When playing Minecraft, if you want to jump off a tree into water just for fun, DON'T!! You will misjudge the distance between the tree and the lake, land on the "beach," and take about 3 1/2 hearts worth of fall damage.

When playing an online game on a public computer involving the manipulation of variously colored balls dropping down upon an icy mountaintop, don't forget where you are and exclaim, "Oh, no, my balls froze up!" The people next to you will laugh but the librarian on duty will not see the humor in it and will keep a clandestine surveillance of your internet activities for the next two hours.

Ever thought of playing an old-school horror game at night when you're so confident that you'll be just fine? Dear god, just don't. You'll regret your ego soon enough, and you WILL NOT be able to sleep for the next couple days... maybe a week if it gets that bad.

When you see a barrel outside the super market, don't reflexively try to search it for salt piles. You're really outside the supermarket, not playing Skyrim. All the clerks will look at you weird.

When buying a rare videogame soundtrack CD, make sure it's not a Taiwanese bootleg. And that there isn't an official sealed one costing $10 less for sale at the same time. #LFMF
