LOS ANGELES — Mayor Eric Garcetti used the F-bomb in declaring it a big day for LA, bringing 19,000 hockey fans to their feet, lighting up the Twitterverse in delight and, oh yeah, left some folks scratching their heads, wondering just what the ... heck the normally soft-spoken elected official was thinking.

“There are two rules in politics,” Garcetti told those celebrating the Kings Stanley Cup victory. “They say never ever be pictured with a drink in your hand. And never ever swear.

Then he added dramatically: “But this is a big f---ing day. Way to go, guys.”
