Jennifer Carpenter, 33, star of Showtime's hit Dexter (Sundays, 9 P.M.) is a glass-half full kind of gal.

"And I have a $2 bill - my sister says money attacks money!" Other essentials?

Getting Inked

"If there's a great pen at a restaurant or hotel, I ask if I can take it. I don't believe in stealing them -- bad karma! I have one from the Maritime Hotel in New York City."

She's Got Game

"I'm addicted to playing Scrabble on my iPhone. My photos and music are also on there. I have Velodyne headphones -- they're awesome!"

Caffeine Fiend

"Coffee is the love of my life. People who really know me give me Starbucks cards. I have a bunch, all with $4 or $5 on them."

Butter Up

"Korres shea butter lip balm is the best. Delta flight attendants give it out to first class passengers in a case with lotion and a toothbrush."

Spare Pair

"I'm on a bowling league. I always have some Paul Smith socks with me, just in case I wear sandals to a game. We made it to the finals!"
