Stickers
For those who desire to put sticky things on inanimate objects, The Oatmeal shop is now selling stickers. You can buy an 18 pack of stickers for $6.00, or buy an eye-squishingly marvelous Oatmeal Bumper Sticker for three bucks. There's free shipping, too.
All stickers are printed on high-grade vinyl which can be used both indoors and outside. The paper uses high-gloss ultraviolet coating, and can stand temperatures from -10°F to +200°F, so unless you're planning on traveling into outer space or windsurfing on the surface of the sun, these stickers should stand up to pretty much anything. We also advise against sticking these to fast-moving animals such as cheetahs or caribou.
