Want to talk Last Comic Standing with one of its "potential" (ahem) finalists? Esther Ku is offering a live chat on her site at 10 p.m. Eastern once tonight’s semifinals show from Vegas ends. I’ve already warned Ku to watch out for the crazies!

Related: Ku was a guest last week, along with Richard Lewis, on NPR’s Talk of the Nation to talk about the business of stand-up comedy. You can listen to the half-hour interview and call-in segment here.
