Sanjay and Craig

''Did you hear the joke that starts with the guy on the farm...And at the end he says, ‘That's-a no potato, that's-a my poop!' '' No, that snippet isn't lifted from a primetime singlecamera sitcom. It belongs to Sanjay (Maulik Pancholy), the 12-year-old whose best friend is Craig (Chris Hardwick), a snake that only he knows can talk. From the producers of Gen-Y classic The Adventures of Pete and Pete, this newcomer has all the winking humor and sweetness of Ren & Stimpy, Calvin & Hobbes, and Phineas and Ferb, along with a premiere episode plot about ''the world's first butt transplant.'' If the fictional writers room in 30 Rock had to come up with a kid's show, it'd look something like this. A– — Ray Rahman
