Actually, they’ve never even met, but they have one thing in common: They both were interviewed by Steve last month. The Caveman is comedian and actor Kevin Burke, who has clocked more than 1,500 performances in “Defending The Caveman” first at the Golden Nugget, then the Excalibur and now Harrah’s Las Vegas. And the chip monk is the nickname earned by Arthur Nelson, the organist who has cashed in casino chips for Guardian Angel Cathedral on the Strip for decades.   In Banter: Sahara closing, Celine opening, geocaching shut down, earth-moving extravagance ramps up, Rumor for rent and Gladys on the cheap.   las vegas, gambling, chips, religion, caveman, history, shows, harrahs,
