Warriors' tip-off luncheon in S.F. brings out the laughsThe San Francisco Chamber of Commerce hosted its annual "Warriors Tip-Off Luncheon" on Tuesday, a chance to welcome in the 2015-16 NBA season and drum up excitement over the team's potential move to the city in 2018.The first laughs of the afternoon came while San Francisco Chamber of Commerce President and CEO Bob Linscheid was at the podium.Warriors TV play-by-play man Bob Fitzgerald interviewed Lacob and Guber, asking them what their lives have been like since bringing the Bay Area its first NBA title in 40 years.The players were then called to the stage, and Curry poked fun at himself for fouling out after playing just 19 minutes in Monday's exhibition opener.Fitzgerald tried to bait the players, reminding them of naysayers who say the Warriors got lucky in winning their title against the injury-plagued Cavaliers and the media coverage of the splashy offseason moves by the Spurs, Rockets and Clippers.
