Dexter star Michael C. Hall and professional funny lady Sarah Silverman used Labor Day weekend to get to know each other better. According to RumorFix, the two were spotted flirting it up while lunching with friends in West Hollywood.

“They were pinching and tickling each other — they looked like more than just friends,” says a source. Still, the lunch may have been strictly platonic. After all, Michael has also recently been linked to Vanessa Abrue, a Showtime staffer, and he's certainly been known to indulge in a workplace romance. Jennifer Carpenter, anyone?
