Quick, alert Buffy and Giles! Looks like there's a possible blonde vampire on the loose, with suspicious red marks on her teeth and a habit of going out every single night—
Oh, wait. It's just Paris Hilton with lipstick on her teeth. The socialite has been using brighter lip colors than usual, but it looks like she's still figuring out how to keep the lipstick from migrating. It happens to everyone, I guess.

After applying the lipstick, wash your hands and put your index finger directly into your mouth. Close your mouth around it, and pull out your finger. Doing so transfers the excess color to your finger, not your teeth. Of course, it doesn't hurt to check in the mirror before going out, but this simple move should do the trick!
