Richard Kind — best known for his roles on “Spin City” and “Curb Your Enthusiasm” — provided some levity at the weighty American Israel Public Affairs Committee conference Monday in Washington, DC. As host, Kind cracked, “Good evening, ladies and gentlemen. We are gathered here tonight to select a new pope” in front of politicos including Joe Biden and Ehud Barak. “It’s a great night for Israel. It’s a great night for Israel-American relations. It’s a terrible night for Chinese restaurants,” was another hit line. “I killed it,” Kind told us at a Cinema Society premiere of “Oz the Great and Powerful” Tuesday, as he re-enacted the routine. He brought daughter Samantha to a Gucci party at Harlow.
