STATUS: MARRIED, TO WRITER HOLIDAY REINHORN
SEE HIM ON: THE OFFICE
, AS THE LOVABLY NEUROTIC DWIGHT
• THE SECRET TO HIS SEXINESS
"I have excellent personal hygiene and I'm funny. Women dig funny guys, even when they look like trolls. That's always worked for me."
• GEEK CRED
"During high school I was in the marching band, debate club, computer club and on the chess team. I still play chess. I'm all about speed chess."
• SWOON FACTOR
"I like women with tattoos. I melt for dangerous women. That's actually on a bumper sticker on my Prius."
SEE HIM ON: HEROES
, AS A SAMURAI-SWORD SWINGING TIME TRAVELER
• THE UPSIDE OF BEING FAMOUS
"When girls come up and want to snuggle with you or lay a fat one on you, that's quite a compliment!"
• HIS PERSONAL SUPERHERO UNIFORM
"I like to wear a nice shirt or a blazer with jeans. But I feel sexy if I feel comfortable, even if that means I'm going around in sweats."
• THE KEYS TO ROMANCE
"I used to write love songs in college, so if I really wanted to go all-out for a date, I would rent a concert hall, bring out a baby-grand piano and sing one of my songs. I find having a romantic dinner on an empty stage a sexy thing."
SEE HIM ON: CHUCK
, AS THE COMPUTER GEEK AND PART-TIME SPY
• GETTING HIS GROOVE ON
"I can destroy a dance floor. I think life should be a musical. I always hate it when people watch a musical and they go, 'Oh, it's so unrealistic, no one just breaks into song in the middle of their day.' Yeah, they do–if they're me."
• ON KISSING GUEST STAR RACHEL BILSON
"She's 5'2" and I'm 6'4"–lots of apple boxes were used to do those scenes, which were steaming hot."
• UNDER THE COVERS
"I'm naked. I don't understand the point of wearing clothes to bed. Why? Unless you're really cold or sick and you've got to layer up to sweat it out."
STATUS: MARRIED, TO ACTRESS ANEL LOPEZ GORHAM
SEE HIM ON: UGLY BETTY
, AS AMERICA FERRERA'S LOVE INTEREST
• WHAT BRINGS OUT HIS INNER NERD
"Video games. At work America and I have been playing Guitar Hero like a couple of teenagers."
• THE FALLOUT FROM HIS RECENT UNDERWEAR SCENE ON BETTY
"Afterward, one of the producers came up to me and said, 'I have to be honest with you, I thought they digitally put your head on someone else's body.' That's how surprised people were. Now everybody's coming up to me for exercise and diet tips."
SEE HIM ON: THE CW'S GIRLFRIENDS
, AS THE DORKY BEST GUY FRIEND
• DATING, NERD-STYLE
"I've got Star Wars
action figures covering whole walls of my house. I'm not going to take them down. A date can always move the light saber out of the way and sit down if she wants."
• WHY GEEKS ACT
"It's the perfect job for shy people. They tell you what to say, pick out your clothes and comb your hair. I wanted to be on TV because I thought women would approach me more so I wouldn't have to go, 'Hey baby' all the time."
