I can't really say that the whole episode tonight was funny. The only funny parts were with Shatner, Jean Smart and Lee Majors. The part with Henry dropping his cell phone and other things down the dispose-all was lame. The scenes with the ex-boss donating her eggs and the dog eating them wasn't funny either. They should just retool the show and leave the idiot sons out.
I thought the opening with Shatner telling his DIL about his sex life with Jean Smart was kind of funny. But again, that was a scene with Shatner.
I think it's Shatner's misfortune they couldn't find a better concept and supporting cast to work with him. As I said a couple of weeks ago, he still brings the funny, but he's about it on the show.
