Want to be sure you leave your kissing partner tingling with excitement? Morphine Lips might be the answer: the new product -- inspired by Kill Hannah's song "Lips Like Morphine" -- numbs your lips for a kiss "they will never forget."

Vitamin E, beeswax, shea nut, coconut and grape seed oil, jojoba -- there are no surprises in the list of lip balm ingredients until you get to the benzocaine, a local anesthetic agent normally used in everything from first aid sprays to condoms.
