     For these people, looking different isn't just for October 31.

     Star Wars Forever

     The force will always be with Luke Kaye. That's because this dedicated fan has covered his back,

arms, and legs with tattoos(纹身) of Star Wars characters.

     Kaye got his first tattoo about six years ago. Once he started, he just couldn't stop. "I kept seeing

characters in the movies and thinking, 'That would make a great tattoo!'" he says. Kaye also collects

items related to Star Wars. He recently had to sell a large part of his collection because it became too

expensive to store it. But he can keep the tattoos forever.

     "I am nowhere near finished yet," says Kaye, who lives in England. He plans to get tattoos of large

spaceships down his sides. "You never know with me," he adds, "I could come home one day with my

whole face tattooed.”

     The Hole Story  

     "People often just want to look at me or touch me," says Elaine Davidson. It's no wonder. Davidson,

who lives in Scotland, is covered with nearly 7,000 piercings (穿环)! According to Guinness World

Records, she is the most pierced woman on Earth.

     Together, Davidson's studs(耳钉) and rings weigh almost seven pounds. She never removes them.

She keeps them on even when she goes through scanners at airports. All she takes off is her watch!

     In June, Davidson made news when she got married. Opposites must attract. Her new husband has

no piercings at all.

     Goo Goo for Gaga

     Lady Gaga is famous for her outrageous looks. She has worn everything from a dress covered in

bubbles to a coat made out of Kermit the Frog dolls. At the 2010 MTV Music Awards, she even wore

a dress made out of raw meat!

     Some stars try not to stand out in public when they are not performing. They might wear sunglasses

and a big hat when they go out, hoping that no one will recognize them. Lady Gaga, has a distinctive

(与众不同的) approach. She dresses up whether she’s walking through an airport or going shopping.

She might wear a wild wig (假发), a lace bodysuit, or 12-inch heels. She jokes, "I am just trying to

change the world."
