Two months after star David Chappelle suddenly stopped showing up for work on Chappelle's Show, his boss still is awaiting a return date. "The ball's in Dave's court," said Comedy Central president Doug Herzog at the TCA press tour. Herzog elaborated to say that he recently bumped into Chappelle, only to be told the comic needs more time away from the grind. "If you see [Dave], tell him to phone home," the exec quipped.
