This is from Guinness World Records: "Elbow Licking. Contrary to popular urban legend, it is quite possible to lick your own elbow. Guinness World Records receives about five claims a day for this and stresses the following point: Being able to lick your own elbow is not, in any sense, a world record. If you're one of the rare few who can lick your elbow, save it for the water cooler."

It is possible to lick your own elbow. There is an urban legend that says that it is impossible to kiss your own elbow and if you do, it says you will turn into the opposite sex. Of course this is not true.
