Zachary Quinto, who plays the revered Mr. Spock in J.J. Abrams' popular Star Trek movie reboot, turns 32 today. He returns to his regular gig, as resident supervillain Sylar, on NBC's Heroes this fall. (If you missed it, catch the very odd viral video featuring Quinto and a lot of spilled milk below.) You love him as "The Mac Guy" on those commercials, so everybody wish Justin Long a happy 31st birthday. You can see on the big screen these days in Sam Raimi's horror flick Drag Me to Hell. Saturday Night Live’s Dana Carvey (you know him from Wayne’s World) turns 54. Improv king Wayne Brady, formerly of Drew Carey’s Whose Line Is It Anyway? and now host of Fox’s Don’t Forget the Lyrics, is 37. Prison Break star (and Channing Tatum lookalike) Wentworth Miller also turns 37 today, and NASCAR driver Kyle Petty is 49.
